GNU Info (grep.info)Grep Programs`grep' programs *************** `grep' searches the named input files (or standard input if no files are named, or the file name `-' is given) for lines containing a match to the given pattern. By default, `grep' prints the matching lines. There are three major variants of `grep', controlled by the following options. `-G' `--basic-regexp' Interpret pattern as a basic regular expression. This is the default. `-E' `--extended-regexp' Interpret pattern as an extended regular expression. `-F' `--fixed-strings' Interpret pattern as a list of fixed strings, separated by newlines, any of which is to be matched. In addition, two variant programs EGREP and FGREP are available. EGREP is the same as `grep -E'. FGREP is the same as `grep -F'. automatically generated by info2www version 1.2.2.9 |
