About 2 weeks ago, someone brought to my attention that our script
to periodically merge /etc/motd.public into /etc/motd wasn't
running. When I looked into it, the cron daemon was running, but
there hadn't been any root activity in the log since April 7th. I
looked into it for a while, but got lost in other things I was

expressions in a file? Basically I want to combine "grep -f <file>"
to store the patterns and awk's $3 ~ /(AAA|BBB|CCC)/ ... I realize
I can do this with "egrep -f " and use regexp instead of strings, but
was wondering if there was some magic way to do this.
\_ UNIX has no magic. Make a shell script to produce the ask or egrep

\_ our "sysadmin" today deleted /home. When we asked her why
she said she didn't do it. When I checked the sudo logs,

2010/4/22-5/10 [Computer/SW/Languages/Misc] UID:53797 Activity:nil | 4/22 In Linux is there an easy way to rename the scripts in /etc/rc?.d ?
For example I want to set all the /etc/rc?.d/S91apache to S100apache
so that it'll run the ramdisk BEFORE going to apache.
\_ Sure, just move them.
\_ I mean is there a script that will rename all of them
for me? Like: setrc apache2 0 0 1 1 1 1

2009/8/19-9/1 [Computer/SW/Unix] UID:53285 Activity:nil | 8/18 Hi again, new freebsd guy here again, in bash I was able to go
LD_LIBRARY_PATH=/opt/foo/lib ./runmyapp
I managed to do this in tcsh by using setenv in a shell script
that setenv's the lib path and then executes $1, just wondering
if there was a way to do it in 1 line from the cmd line as in bash?
Thanks, btw %2c or %3c worked. Freebsd, tcsh and vi forever!

rather not if there is a standard way of doing this. I'm

are Perforce and Subversion. Anyone worked with both and have good
arguments one way or the other? (These are the only two options we
have.) We're most interested in client performance, ease of use, and
reasonable branching.

2009/8/21-9/1 [Computer/SW/Unix] UID:53297 Activity:nil | 8/20 When I use rsync to backup, it's pretty cool except in cases where
I rename a directory name from the source. Rsync will just do
a plain copy. Is there a program that'll detect renaming of
directories (by checking for children files), or at least
move them to a dated directory?
\_ Not related but beware of using rsync as a backup tool.

2009/4/27-5/4 [Computer/SW/Unix] UID:52913 Activity:nil | 4/27 Git, Darcs, or Mecurial?
\_ If you do not need and will not want anyone on Windows, Git is OK.
I'm partial to Mercurial, since it's simple, and doesn't pollute
my directories with .svn, it just has a top-level .hg directory.
I hear darcs is good if you want to allow multiple people editing
the same file, since you can merge different changes within a file.
