Hi mike, and thanks list (I've been using grep something *, grep
something */*, and so on, for years and now feel like Dorothy of Oz!)
You could write a very simple shell-script called rgrep.sh and then alias a
command (depending on what shell you use in Unix) called rgrep. (Or just
chmod 755 rgrep.sh and put it in a directory that is in your PATH.)
Shell scripts begin with a single line like this:
#!/bin/sh
You can use if/else, case, and various test statements in shell scripts,
and substitute (this may be tcsh-dependent) "$1" meaning "the thing typed
on the command line after the command," in this example, rgrep
expressionhere so $1 gets substituted for expressionhere.
Shell scripting is useful -- I find -- to simplify very long commands that
require you to escape certain punctuation and spaces by using the "force"
*grins* OWKA "\" as in:
$ grep -i an\ example\ using\ spaces ~/myfile.txt

If it is written in perl, then just make sure perl is installed on your
system (find out by typing which perl, or just the word perl), and if so
you are in luck to use the old script, provided it doesn't have any "exec"
calls that clash with whichever shell you use or are using.
