Is it possible to get the filename of a sourced file (either Csh or Sh) while the file is being sourced? For example, can you have a sourced file echo its pathname? Something like: % source <some_path_name> I am <some_path_name> Curious, Glenn -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Glenn Boysko clsi!glenn@uunet.uu.net

Not easily. There is, however, a useful trick in the other direction: If you start a script with #!/bin/echo sorry,try:source then someone who executes it without typing ``source'' will be warned what to do. This makes a convenient wrapper for tset-type programs. ---Dan

I had to do this once! What I had to do was create an alias:
alias mycmd "set my_argv = ( \!* ); source myfile"
then `myfile' could go around using `my_argv' like scripts use $argv;
Big drawback to this approach is that you have to be real carefule not
to stomp on things in the environment since you are NOT a separate shell.
You should probably take care to unset any variables that you used and
be REAL careful not to overwrite any pre-existing variables (unless you
know what you are doing with the variables in question).

Just enclose your alias' 2nd parameter in '( and )', ala: alias mycmd '( set my_argv = ( \!* ); source myfile )' and you will run in a subshell. -- BURNS,JIM Georgia Institute of Technology, Box 30178, Atlanta Georgia, 30332 uucp: ...!{decvax,hplabs,ncar,purdue,rutgers}!gatech!prism!gt0178a Internet: gt0178a@prism.gatech.edu

If stest is sourced from another sourced script then it will show the outer script name. And if it is sourced from a script executed in a subshell then there won't be any history maintained for that shell. -- Barry Margolin, Thinking Machines Corp. barmar@think.com {uunet,harvard}!think!barmar
