Example 2-1: The grep command

• To find number of Pg phases in file collect.out given in directory example1, we run command grep “Pg “ collect.out on the command line,

[aghods@ghods example1]$ grep "Pg " collect.out

PRN GZ EPg 9 D 1850 3.25 117 0.06 0 29.6 242

ALA GZ EPg C 1850 3.70 113 -0.4610 35.4 153

FIR GZ EPg D 1850 11.17 93 0.1010 81.3 172

SHM GZ EPg D 1850 12.05 93 0.2110 86.1 136

.....

The number of lines with Pg word is large so I did not show all of them here. Please notice that [aghods@ghods example1]$ is not part of the command and it is part of command line and its form depends on your setup. You should only type the command (grep “Pg “ collect.out ) in the command prompt to get above result.
