Search a file for a pattern using full regular
expressions.
egrep [-b] [-c] [-h] [-i] [-l] [-n] [-s] [-v] [-x] [ -e pattern_list ] [-f file ] [ strings ] [ file]
| -b |
Precede each line by the block number on which it was found. This can be useful in locating block numbers by context (first block is 0). |
| -c |
Print only a count of the lines that contain the pattern. |
| -h |
Suppress printing of filenames when searching
multiple files. |
| -i |
Ignore upper/lower case distinction during
comparisons. |
| -l |
Print the names of files with matching lines once, separated by NEWLINEs. Does not repeat the names of files when the pattern is found more than once. |
| -n |
Precede each line by its line number in the file (first line is 1). |
| -s |
Work silently, that is, display nothing except error messages. This is useful for checking the error status. |
| -v |
Print all lines except those that contain the
pattern. |
| -x |
Consider only input lines that use all characters in the line to match an entire fixed string or regular expression to be matching lines. |
| -e pattern_list |
Search for a pattern_list (full regular expression that begins with a -). |
| -f file |
Take the list of full regular expressions from file. |
| strings |
Specify a pattern to be used during the search for input. |
| file |
A path name of a file to be searched for the
patterns. If no file operands are specified, the standard input will be used. |
