bash - How to replace a command with the result of another in linux?

Sunday, 22 December 2019

I want to create a command which uses the result of another like this:

JNLP_FILE='find . -name viewerApplet.jnlp'
cp ${JAR_FILE} ../../sign-jar/$PROFILE/

But I don't know how to execute the find command to use for the 'cp' command.

Any help?

Answer

You can use a dollar sign followed by the command in parentheses [$()] to have the output of that command fed directly into the command line:


cp $(find . -name viewerApplet.jnlp) ../../sign-jar/$PROFILE/

Alternatively, you can use backticks (`):


cp `find . -name viewerApplet.jnlp` ../../sign-jar/$PROFILE/
