kandi X-RAY | pipestatus Summary

pipestatus is a Shell library typically used in Utilities, Command Line Interface applications. pipestatus has no bugs, it has no vulnerabilities and it has low support. You can download it from GitHub.

pipestatus - source file for posix shell that allows to obtain an exit status of every program in a pipe. home page: when we program in shell we often run pipes like this. posix says that exit status of pipe is the exit status of last program in it, i.e. progn in our example. that is, exit status of all other programs in pipe is silently ignored. but in many situations exit status of all programs in pipe should be checked to make program robust. some shells like bash and zsh have special extensions for doing this but posix shell unfortunately doesn’t provide an easy way for doing this. in short, this is why i wrote this piece of code, packaged it and make it publicly available. provided functions: runpipe_base, runpipe, runpipe0, runpipe_re, check_status, check_status0, check_status_re. usage for 'runpipe*' functions: runpipe_base prog1 [args1] '|' prog2 [args2] '|' … runpipe prog1 [args1] '|' prog2 [args2] '|' … runpipe0

How to use the following command from R: echo "${pipestatus[1]}"?

Asked 2020-Nov-04 at 11:12

I need to check the exit status of a piped command from R on Debian, like here, but cannot make run echo "${pipestatus[1]}" successfully from R using system2/system function. The command works properly when I use command line.

The command I am trying to use in R can look like this (the shell I use is zsh):

ANSWER

Answered 2020-Nov-04 at 11:12

You can’t use zsh features here, since system2 doesn’t invoke a shell.

Instead, you’ll either need to use a raw system call or, better, explicitly invoke the shell in system2. You’ll also need to use double quotes instead of single quotes around ${pipestatus[1]} to allow expansion — otherwise zsh will interpret it as a literal string.

PIPESTATUS[0] in BASH script

I am implementing a scenario in Unix Bash scripts. I have two scripts ABC.bash and XYZ.bash. There is one condition in ABC.bash when requester does not enter Y or y scripts exit with message and do not work further. ABC.bash working fine when runs alone.Problem arises when I run it from another bash script i.e. XYZ.bash. It does not check for exit condition. Syntax of logic in XYZ.bash.

The problem is that PIPESTATUS is a volatile variable. That is it will be reset as soon as any other command is executed. You need to remove the call to sleep 2 if you want to inspect the PIPESTATUS.

QUESTION

Display stdout and stderr to both console and file, color stderr red and display stdout and stderr as they are being produced

Asked 2020-Jul-29 at 00:18

I have a strict requirement of having *stdout* and *stderr* being simultaneously redirected to both a console and a file, with *stderr* output being colored red.
Additionally, *stdout* and *stderr* lines should be displayed in the order they are being produced (I'll explain better what I mean with this).
My issue is achieving this altogether in a bash script, as each individual steps are not really a big challenge.

a) Display *stdout* and *stderr* to both console and file
There's a lot of information how to achieve this. Something like: ...

namely because now mycommand's stderr is only being displayed after I exit my app

How to have stdout and stderr to both console and file, having red stderr lines and "stdout and stderr being displayed as they are being produced" (See Fig.1)?

Both stderr and stdout of your program become block buffered when the output is not a terminal. stdout is block buffered because mycommand is not outputting to the terminal and seds output is not a terminal and it's outputting stderr, so stderr becomes also block buffered. Configure your program to configure it's stdout/stderr to be line buffered, or you could potentially set initial buffering with stdbuf -oL -eL and use sed -u or stdbuf -oL sed.

How to get the EXIT_CODE value outside the function body?

Create a temporary file.
Write $EXIT_CODE to a temporary file.
Read that file.

or return the exit code from your function and use PIPESTATUS as you did.

Passing values between jobs and stages

There is currently no way in GitLab to pass environment variable between stages or jobs.
But there is a request for that: https://gitlab.com/gitlab-org/gitlab/-/issues/22638

Current workaround is to use artifacts - basically pass files.
We had a similar use case - get Java app version from pom.xml and pass it to various jobs later in the pipeline.

How we did it in .gitlab-ci.yml:

How set an exit code when exiting bash?

I want to run a command from a sub-bash and I need the return code from it; actually it's running a pipeline and I need the PIPESTATUS array, or at least one component.

This was my best guess and it does not work. I just get a 0. Since bash did not error it makes sense, it's just not what I need. Help?
