I have a shell script (set_up_my_ls_colors.sh) that, if I call from my shell, it configures my color scheme for ls. The nice thing about the script is that it allows me to configure colors in a human-readable format. The file works well under zsh and bash, but it does not work well in tcsh.
If I call it as:
. ~/.set_up_my_ls_colors.sh
I get:
.: Permission denied
even though the file has u+x permissions.
I have also tried with
/bin/tcsh ~/.set_up_ls_colors.sh
which returns
Illegal variable name
Below is the file set_up_my_ls_colors.sh in question:
# Call this script as . ~/path_to_this_file.sh
export LS_COLORS=$( \
( grep '\w' | grep -v '^#' | sed 's/#.\+//' | perl -lane 'printf "%s=%s:", shift @F, join ";", @F;' ) <<< "

It's not working for a couple of reasons:
To run a script as an executable the first line has to tell the shell what program (i.e. which shell) should run the script, so you should start:
or whichever shell you want (but see the note below).
Secondly, you can't execute this in tcsh because it uses a different syntax. You don't
exportenvironment variables, you usesetenvwith no equals sign. Additionally, $(command) means nothing to tcsh.Another problem though is that if you run this script from a different shell, the variables set in it won't be carried back when it completes: when you run
. ./script.shit runs the script through the currently running shell.Your best solution is to have two versions, one in this format, and one that works with tcsh, and to put them in your startup scripts, i.e ~/.bashrc or ~/.tcshrc.
