Search a file for a fixed-character string.
fgrep [-b] [-c] [-h] [-i] [-l] [-n] [-s] [-v] [-x] [ -e pattern_list] [-f pattern-file] [pattern] [ 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 files when searching multiple files. |
| -i | Ignore upper/lower case distinction during comparisons. |
| -l | Print the names of files with matching lines once, separated by new-lines. 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 | Print only lines matched entirely. |
| -e pattern_list | Search for a string in pattern-list (useful when the string begins with a -). |
| -f pattern-file | Take the list of patterns from pattern-file. |
| pattern | 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. |
