recursion
I'm using the UNIX csh and i wish to use recursion to nav my way up (or down as it is) a given folder.
My little test script is called "r" and takes a folder as argv[1] (or $1)
#!/bin/tcsh -f
set allFiles = `ls -A $argv[1]`
cd $argv[1]
while ($#allFiles)
if (-d $allFiles[1]) then
echo $allFiles[1]
# do whatever...
r $allFiles[1]
endif
shift allFiles
end
echo done.
however once it chages into a given dir the script "r" is no longer in the new dir and thus the process fails. I'm not the super user so I can not dump the script "r" in "bin". Can anyone help me do something similair?

shells
shells(4) File Formats shells(4)
NAME
shells - shell database
SYNOPSIS
/etc/shells
DESCRIPTION
The shells file contains a list of the shells on the system. Applications use this file to determine whether a shell is valid. See getuser-
shell(3C). For each shell a single line should be present, consisting of the shell's path, relative to root.
A hash mark (#) indicates the beginning of a comment; subsequent characters up to the end of the line are not interpreted by the routines
which search the file. Blank lines are also ignored.
The following default shells are used by utilities: /bin/bash, /bin/csh, /bin/jsh, /bin/ksh, /bin/ksh93, /bin/pfcsh, /bin/pfksh, /bin/pfsh,
/bin/sh, /bin/tcsh, /bin/zsh, /sbin/jsh, /sbin/sh, /usr/bin/bash, /usr/bin/csh, /usr/bin/jsh, /usr/bin/ksh, /usr/bin/ksh93, /usr/bin/pfcsh,
/usr/bin/pfksh, /usr/bin/pfsh, and /usr/bin/sh, /usr/bin/tcsh, /usr/bin/zsh, and /usr/sfw/bin/zsh. /etc/shells overrides the default list.
Invalid shells in /etc/shells could cause unexpected behavior, such as being unable to log in by way of ftp(1).
