4/19    Stupid sed question:  I know you can use UNIX environment variables
        in a sed script by double quoting at the command line, i.e.:
        sed "s/_momma_type_/$MOMMA/g" input.file
        will be expanded by the shell before execution so that _momma_type_
        will be substituted with whatever the value of $MOMMA happens to
        be.  Is there anyway do this in a sed script specified by sed -f?
        or do I have to use a shell script to get shell substitution?
        I'm guessing the latter, but I thought I'd ask just to be sure.
        \_ Environment variable substitution is handled by the shell.
        \_ You can do it in Perl. I don't know sed. Sounds like sed sucks.
           \- i use sed and awk for a lot of stuff but if you are writing
              enough sed to need to put it in a file, yeah use perl. --psb

8/29    There was once a CSUA web page which runs an SSH client for logging
        on to soda.  Does that page still exist?  Can someone remind me of the
        URL please?  Thx.
        \_ what do you mean? instruction on how to ssh into soda?
           \_ No I think he means the ssh applet, which, iirc, was an applet
              that implemented an ssh v1 client.  I think this page went away

9/20    How do I change my shell? chsh says "Cannot change ID to root."
        \_ /usr/bin/chsh does not have the SUID permission set. Without
           being set, it does not successfully change a user's shell.
           Typical newbie sys admin (on soda)
           \_ Actually, it does: -rwsr-xr-x 1 root root 37552 Feb 15  2011 /usr/bin/chsh

9/24    How come changing my shell using ldapmodify (chsh doesn't work) doesn't
        work either? ldapsearch and getent show the new shell but I still get
        the old shell on login.
        \_ Scratch that, it magically took my new shell now. WTF?
           \_ probably nscd(8)

3/29    A friend wants a PC (no mac). She doesn't want Dell. Is there a
        good place that can custom build for you (SSD, large RAM, cheap video
        card--no game)?
        \_ As a side note: back in my Cal days more than two decades ago when
           having a 387SX made me the only person with floating-point hardware,
           most machines were custom built.

4/27    I wrote a little shell script to collect iostat data:
        DATE=`date +%m%d`
        while true

1/27    Interesting list of useful unix tools. Shout out to
        cowsay even!
        \_ This is nice.  Thanks.

10/24  What's an easy way to see if say column 3 of a file matches a list of
       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

5/19    If script A runs, and calls script B ..... is it possible for me to exit\
        script A based on results of script B and not continue?
        \_ assume any shell
        \_ Yes.
           \_ without passing the result to some stupid temp file?
              \_ It sounds like you want "scriptb || exit", which will run
