Shell Command for Symbolic Link Targets
**DUP post in Shell Programming and Scripting ***
Hello,
I'm still learning the ins and outs of how to combine multiple Unix commands together (specifically AIX), but I'm looking to do the following (only on local files):
1. Find all symbolic links that are not set up using absolute pathnames
2. Find all symbolic links that are broken (ie, target does not exist).
My original idea was to find all symbolic links, pipe it to a file and then read the file, but we'd like to do it as a single command without creating new files.
I've only been able to come up with the following (which I believe shows all the local symbolic links):
find / -type l \( -fstype jfs -o -fstype jfs2 \)
Thanks for any and all help.
Ben
edit: I think I may have found the answer to #2, is it correct?
find / -type l | (while read FN ; do test -e "$FN" || ls -l "$FN"; done)

Hi all
Ive been given the task to write a script that tests that certain link files work, i.e. the physical directory the link points too, is actually there.
Now, before I go down the route of ls -l | awk ...... or using test or find, is there a far more simpler command that I can use ?

CPANPLUS::Shell::Default::Plugins::Source(3pm) Perl Programmers Reference Guide CPANPLUS::Shell::Default::Plugins::Source(3pm)
NAME
CPANPLUS::Shell::Default::Plugins::Source - read in CPANPLUS commands
SYNOPSIS
CPAN Terminal> /source /tmp/list_of_commands /tmp/more_commands
DESCRIPTION
This is a "CPANPLUS::Shell::Default" plugin that works just like your unix shells source(1) command; it reads in a file that has commands
in it to execute, and then executes them.
A sample file might look like this:
# first, update all the source files
x --update_source
# find all of my modules that are on the CPAN
# test them, and store the error log
a ^KANE$'
t *
p /home/kane/cpan-autotest/log
# and inform us we're good to go
! print "Autotest complete, log stored; please enter your commands!"
Note how empty lines, and lines starting with a '#' are being skipped in the execution.
