Table 1. Grep and awk text processing programs.

NAME:    grep  
EXAMPLE: grep DSEU001 datafile.out   
         Prints only the lines in datafile.out that have DSEU001 
         anywhere on the line.
NOTES:   general regular expression parser. Also claimed to be 
         named from a common series of commands in the UNIX ed 
         line editor (/g/r/e/p).

NAME:    awk
EXAMPLE: awk '/^9/{print $2, $1}' datafile.out
         Prints the second, then first fields of each line in 
         datafile.out that begins with a 9.
NOTES:   awk is named after its developers, Aho, Weinberger, 
         and Kernighan. It is a powerful text processing 
         language with a very terse syntax.
