fgrep(1) OSS Shell and Utilities Reference Manual
EXAMPLES
1. To search several files for a string of characters, enter:
fgrep ’strcpy’ *.c
This searches for the string strcpy in all files in the current directory with names ending in
.c.
2. To count the number of lines that match a pattern, enter:
fgrep -c ’{’ pgm.c
fgrep -c ’}’ pgm.c
This displays the number of lines in pgm.c that contain left and right braces.
If you do not put more than one { or } on a line in your C programs, and if the braces are
properly balanced, then the two numbers displayed will be the same.
3. To display all lines in a file that begin with an ASCII letter, enter:
fgrep -e ’ˆ[a-zA-Z]’ pgm.s
Note that because the fgrep command searches only for fixed strings and does not inter-
pret pattern-matching characters, the following command searches only for the literal
string ˆ[a-zA-Z] in file pgm.s:
fgrep ’ˆ[a-zA-Z]’ pgm.s
4. To display all lines that do not match a pattern, enter:
fgrep -v ’ˆ#’
This displays all lines that do not begin with a # (number sign).
5. To display the names of files that contain a pattern, enter:
fgrep -l ’rose’ *.list
This searches the files in the current directory whose names end with .list and displays the
names of those files that contain at least one line containing the string rose.
6. To display all lines that contain uppercase characters, enter:
fgrep ’[[:upper:]]’ pgm.s
EXIT VALUES
The fgrep command returns the following exit values:
0 (zero) A match was found.
