Testing for Executables

[Joaquin Menchaca]

I did this, but is there a cleaner way?

[ -z $(which wget) ] && { echo "ERROR: Wget not found. Install wget"; exit 1 ; }

I would recommend not writing it all in one line (https://google.github.io/styleguide/shell.xml)

What about:

which wget 2>&1 >/dev/null

code=$?

if [[ $code -ne 0 ]]; then

    echo "ERROR: Wget not found. Install wget"

    exit $code

fi

However, if you must do it on one line:

[[ $(which wget) ]] && { echo "ERROR: Wget not found. Install wget"; exit 1; }
