=== Conditional echo/eval I have the following simple script (test and do): {{{c #!/bin/bash if [ "$TDOCONF" = "y" ]; then "$@" else echo "(tdo:) $@" fi }}} now if {{{$TDOCONF}}} is not set to "y", then it echoes its arguments. If not, it does them. Note that it must be exported via {{{export TDOCONF=y}}} for the script to see it. This makes it easy with loops over files to check what they will do, then run them, without having to edit {{{echo}}} commands in and out of them.
