Passing arguments to ‘Run Shell Script’ in Automator

automatorscriptterminal

I want to make an Automator workflow to run a shell command. For example, I want to receive text input from the user and treat that input as a shell command instead of text. I have tried passing argument as stdin but still not able to make it work. Here is a simple example of what I am trying to do:

The user input some text, say, 'xyz'. I want to pass this text to shell script as follow

echo "$1/"

to get xyz as the output of the shell script to show in show result action of Automator.

When passing input to Run Shell Script in Automator you need to change Pass input: to stdin to Pass input: as arguments as shown in the example workflow below.

Automator choose finder folder and run shell script

You can simply pass the selected folder to the shell script by selecting "as argument" from the "pass input:" dropdown-menu and then adding "$@" at the point in your script where you want the folder path to be used.

To use drag&drop, just remove the "ask for finder items" action and let the "run shell script" receive the input from "application can receive files and folders as input".

Automator to execute shell script with an input text file, copy it to specific directory

EDIT: Workflow now works with one bug: running the workflow twice results in two copies of the control file being copied

Make a new Automator SERVICE. At the beginning, for "receives selected as input" choose "documents". Add the process "set value of variable" and make a new "destination path" variable (default variable name is "destination path"). Add the process "open finder items" to the beginning to open the control file. Add the process "run applescript" to the workflow the code is the following:

on run {input, parameters}

set LineNumber to (the line in which the path is specified in the control file)
tell application "TextEdit"
    set theVariable to paragraph LineNumber of document 1
    set thePath to POSIX path of theVariable
    set thePath to text 1 thru -2 of thePath
end tell

return thePath
end run

I don't know why this couldn't have been in the same block, but you need to add a separate AppleScript process. The code is as follows:

on run {input, parameters}

tell application "Finder"
    set theFolder to POSIX path of input & "/DEBIAN"
    try
        make new folder in folder input with properties {name:"DEBIAN"}
    end try
end tell

return theFolder
end run

Add the process "set value of variable" and make a new destination path variable (default name is "destination path 1").
Add the "get value of variable" process and get the value of the variable with the path of the input file ("destination path"). Click on "options" on this process and check "ignore this action's input".
After this, Automator has a process called "copy finder items" and this can be used to copy the input (the output of "get value of variable", which is the input file). This worked for me, hope it works for you as well. Good luck :)
