I have a directory with a lot of scripts to generate figures. All the scripts match the pattern fig*

I would like to have a bash script (named to invoke all figure generation scripts. How can I do this?

bash internals:

for s in fig*; do
    bash "$s";

via (gnu)find:

find . -name "fig*" -exec bash '{}' ';'

Unless the scripts require parameters or require to be called in a specific order, you should be able to achieve this via a simple loop


for i in $SCRIPT_DIR/fig*

Caveat: For this to work, the fig* files should specify the interpreter via the #!/bin/bash line. If they do not, you need to invoke the interpreter explicitly by replacing ./"$i" with something like bash ./"$i"

Also, to use ./"$" as in your example, the files need to have execute permissions enabled, while when using bash ./"$i" they don't. – Dennis Williamson Oct 16 '09 at 10:48

Instead of a for-loop, you can use find:

find $SCRIPT_DIR -type f -name "fig*" -exec {} \;

If you want them run in parallel and if you have GNU Parallel http:// installed you can do this:

ls ./fig* | parallel

or even this:

parallel ::: ./fig*
