@scottalanmiller said in beyond bash shell scripting, what language should I use:

Go is great as a language. But like Ruby, not installed generally. And fewer resources. If it was a greenfield new OS, yeah, Go for sure. But for practical reasons, Python I think.

As these are systems that I control, there is no reason Go cannot be installed.

Between your comments and prior ones from @stacksofplates I think I might try Go in order to learn it.

You normally wouldn't install it anyway as it's not a scripting language. You'd just compile your binary and ship that to your systems.

I completely misunderstood that about Go. Okay, I will do a bit of checking and decide what I want to do.

oh sorry, I figured you knew. That's why I never look at it, I don't want to deal with binaries in that way. But nothing wrong with that. Write it on your machine at home, compile, ship binary. Works just fine.

As fixed tasks, this is not a bad solution. So I will keep it in mind.

Right, no big deal in this case.

@stacksofplates docker is worse than reddit. I can’t believe you would suggest such hot garbage.

How is it garbage @VoIP_n00b ? It is quite possible if someone wants to run their Controller as a container. I am not sure why you are also comparing Reddit with Docker, what is the comparison?

I think it's an attempt at trolling.

@Pete-S said in I need this script to email the log it generates:

OK, I understand. Thanks.

Also, I wasn't trying to be abrasive. I kind of worded that strongly. I just don't like Bash much. I find it annoying, so I'd rather use something else unless it's a really simple thing.

No problem. Bash is primitive for sure. Pick the right tool for the job I guess.

@JaredBusch said in Redirecting feedback from Linux command:

@Pete-S Pretty much what I do not want is the status bar from these two commands.

fwconsole ma upgradeall

fwconsole chown

Well, use grep to match for the progress bar then.

First output stderr to a file and look in the file.

I don't know how the progress bar looks when it's output as a stream of characters.
I'm guessing every update is something like

3076094/3076094 [===========>-------------] 60%<CR>

In that case grep for every line that doesn't contain a [ followed by a number of =, > or - and finally a ].

So something like:

grep -v '\[[=->]+\\]'

Or maybe even better:

grep -v '\[[=->]{28}\\]'

Above assuming there are always 28 characters inside the brackets in the progress bar.

PS.
Funny thing but there seems to be a bug in the forum software.
I had to use an extra backslash to get the above regex look right \[[=->]+\\\] instead of \[[=->]+\\]
They look right in the preview though.

@DustinB3403 said in Powershell variable help:

@Pete-S That is going to be complete subjective based on the type of spam that might come in.

I follow what you're saying but I'm kind of stuck between having something functional or not (due to this).

Well, you need to decide what you are allowing and not. For instance you have already decided to just use the subject line and not any of the other parts of the email, for instance author.

You need to run the string through regex or something like that to remove characters you are not allowing. It might take more than one string operation to sanitize. I think you can escape any special character you want to allow with backtick `.

Another option would be to allow the user to enter the entire KQL query themselves.

Also if you get an error when trying to apply the search you put out an error "Invalid search input!" and go back to prompt the user for input again. That would be one way so solve problems.

@Pete-S said in Anyone have a script I can tweak to reencode my h264 media to hevc:

If you have a larger movie collection say 10,000 movies @ 90 minutes runtime, you'll have 30,000 hours of encoding ahead of you before you've finished that job. That will take 3.5 years.

And who would legally have something like that? Anyone who was in that scenario would just ☠ download as needed.

I don't, but had I stayed collecting like I used to, I'd be pretty close at this point.

This is going to save me time. Was just starting to look at this.

@matteo-nunziati said in bash script help splitting string:

try this:

# initializing agi variables declare -a array while read -e ARG && [ "$ARG" ] ; do array=(` echo "$ARG" | sed -e 's/://'`) export ${array[0]}=${array[@]:1} #next added line for debug only. comment this out in prod. echo "${array[0]}=${array[@]:1}" done

if you want to "slice" an array use the syntax: ${array[@]:from:to}, not providing the 'to' arg means go up to the end of array.
source here.

Almost right. Because of the export command parsing spaces, I needed to stick it in a variable first.

# Variable to hold the details for the log file DUMPARG=" Begin Argument dump:\n" # Create an Array to hold the results of the loop declare -a array # Loop through the AGI variables while read -e ARG && [ "$ARG" ] ; do # Dump them into an array, after removing the : array=(` echo $ARG | sed -e 's/://'`) # take the array and create a variable from the first element put the rest as the value # value must be put into a holding variable to parse correctly by the export command val=${array[@]:1} export ${array[0]}="$val" # Dump them into a string for the log file DUMPARG="$DUMPARG $ARG\n" done

Corrected the title to FreePBX instead of FeePBX, lol. Although that name would be useful somewhere, too.

go me

Going to work on this, finally, after dinner tonight.

Thanks for those that posted.

@WrCombs said in How did you learn?:

How did you learn Power-shell scripting?
any books worth looking at? Looking at expanding some more, and I know Automation makes jobs way easier.

This (https://channel9.msdn.com/Series/GetStartedPowerShell3/01) combined with doing tasks in PowerShell. In my opinion, as others have states, it's easier to learn via doing tasks. Added bonus is you complete a task with PowerShell or script it, then see if / how you can improve your script.

ok this is what I came up with.

#!/bin/bash # Send everything to logs and screen. exec 1> >(logger -s -t $(basename $0)) 2>&1 # Variables and descriptions of their use. # Array of dates found in the filename of the backup files. arrDates=() # Number of full backup sets to keep. keep=4 # How many full backup sets have been found. found=0 # Bas path to the backup files, minus the last folder. base="/home/jbusch/" # Full path to the backup files, populated by the script. path="" # This script requires that the final folder name be passed as a paramter. # This is because it is designed to be ran independently for each subfolder. # ex: ./file_cleanup.sh Hartford # ex: ./file_cleanup.sh Seymour #check for the path to be passed if [ ! -z "$1" ] then # Create the full path to be checked based on the passed parameter. path=$base$1 else exit 127 fi printf "Executing cleanup of backup files located in $path.\n" # Loop through all of the files in the path and parse out an array of the file dates from the file names. # All backups are named `backup-0000001-YYYYMMDD-XXXX*`. cd $path for f in backup-* do # The date is from character 15 for 8 characters. arrDates=("${arrDates[@]}" "${f:15:8}") done cd ~ # Sort in reverse order and only show unique dates. arrDates=($(printf '%s\n' "${arrDates[@]}" | sort -ru)) # Loop through the array of dates and check for there to be 4 files for each date. for checkdate in "${arrDates[@]}" do count=$(find "$path"/backup-0000001-"$checkdate"-* -type f -printf '.' | wc -c) if [ $count -eq 4 ] && [ $found -lt $keep ] then found=$((found+1)) printf "Checking $checkdate, we found $count files. We are keeping this date, currently we have $found dates saved.\n" elif [ $count -gt 0 ] && [ ! $count -eq 4 ] then printf "Incorrect number of files '('$count')' found, removing invalid backup dated $checkdate.\n" rm $path/backup-*-$checkdate-* elif [ $count -gt 0 ] && [ $found -eq $keep ] then printf "We have already found $keep full sets of backup files. Removing backup files dated $checkdate.\n" rm $path/backup-*-$checkdate-* else printf "The date $checkdate returned $count files. This is an unhandled scenario, doing nothing.\n" fi done

output look like this

@JaredBusch said in VPS injected ssh keys:

Under no circumstances do I actually want anyone's key tied to the root user. It negates all accountability.

It's for pre-production setup. Not for deploying straight to production.

@JaredBusch said in Need a good example of getting powershell arguments:

I'll hit the google later, because I am on other things, but I found that something I touched today could very easily be improved if I can add parameter handling to the powershell script.

Now, the basics are easy as it is all in the $ARGS variable/object.

But I want to have some safety checking. because it is easier to do things right the first time.

Example: I want a parameter to note if I should make the thing being done the default.

I can pass a 1 like dothing.ps1 1 and I can simply code something to check $ARG[0] eq "1" but that is not very explanatory to the person using the script.

This is more explanatory dothing.ps1 -default for a command.

So has anyone seen a good example of parameter handling that I can put into my dothing.ps1 script?

I'm not sure I understand exactly what you mean.

Taking a guess here, but how I understand is that you'd want to add this at the top of your script:

[cmdletbinding()] param ( [Parameter()] [Switch]$Default ) if ($Default) { Write-Host "The -Default parameter was specified." } else { Write-Host "The -Default parameter was NOT specified." }

Doing that will give you the following output:

PS > .\JBTest.ps1 -Default The -Default parameter was specified. PS > .\JBTest.ps1 The -Default parameter was NOT specified.

If you want to accept input from a pipeline to work with, let me know.
