Unix Commands

Nice

   I think what you basically want to do is '/usr/bin/nice -n 19 command'. 
   nice operates on a command, whereas renice operates on a process id that 
   is already running.

   The syntax for tcsh is 'nice +19 command'

Tar

   Tar has about a million options which makes it a powerful tool. Here are
   my most common uses:

   packing up a directory:

   cd dir
   'tar cvf ~/tmp/newfile.tar .'     

   (the . refers to current dir, c means create
   v means verbose, f means what file to make the archive in)

   To list the contents of a tar file:

   'tar tvf file.tar'

   To unpack a tar file:

   'tar xvf file.tar'    (x is for extract)

    Use the 'gunzip' command, which will replace the compressed file with
    an uncompressed version with teh .gz suffix removed, i.e.:

        gunzip filename.gz

    will replace "filename.gz" with "filename", the uncompressed version.

   If you want to keep the compressed version, and run the uncompressed one
   through a pipe to e.g. untar it or read it or give it another name, you
    can use redirection, e.g.

        gunzip < filename.gz | tar xvf -
        or
        gunzip < filename.gz | more
        or
        gunzip < filename.gz > filename



ps (on Solaris)

    /bin/ps -fu simon

    shows all processes being run by simon
    f = full listing (?)
    u = user

Mounting a floppy on Unix

    mount /floppy

    You can then copy files to /floppy.

    When you are done, type 'umount /floppy'

Who Am I?

   id = who you are!

Where Am I Going?
   
   To the top baby, to the top!

zgrep  

   i.e.

   zgrep simon httpd-xfer.*

Redirecting man pages to a text file

   setenv TERM dumb
   man bash >> bash.txt


Deleting huge files

  find . -type f | xargs rm
