AIM: I would like to tail the last line of the file.txt and input into a variable to use for substitution via sed.

CODE:

 ALARM_POPUP_CONTENT=tail -1 /logs/file.txt

OUTCOME:

This is only outputtin the work 'tail' or an error command not found for the seond option. Any suggestions?

Try:

ALARM_POPUP_CONTENT=$(tail -1 /logs/file.txt)

or with backticks:

ALARM_POPUP_CONTENT=`tail -1 /logs/file.txt`
