If you just want “everything else” that remains after pruning the *.gif, *.png, etc. On the 4th line, you need another -o (it specifies “or” to find), the patterns you DO want, and you need either a -print or -print0 at the end of it. Use as many of these -o -name "." -prune constructs as you have patterns. On the 2nd and 3rd lines, use "*.png", "*.gif", "*.jpg", and so forth. (current directory) is a valid path, for example. On the first line, you specify the directory you want to search. | xargs -0 -I FILENAME grep -IR "pattern" FILENAME o -name "another_pattern_to_exclude" -prune \

If you are not averse to using find, I like its -prune feature:
#Grep options exclude install#
Also, I can’t install anything, so I have to do with common tools (like grep or the suggested find). I can’t search only certain directories (the directory structure is a big mess, with everything everywhere). If there’s a better way of grepping only in certain files, I’m all for it moving the offending files is not an option.

Searching on grep include, grep include exclude, grep exclude and variants did not find anything relevant exclude=PATTERN Recurse in directories skip file matching PATTERN. I know there are the -exclude=PATTERN and -include=PATTERN options, but what is the pattern format? The man page of grep says: -include=PATTERN Recurse in directories only searching file matching PATTERN. As these results are not relevant and slow down the search, I want grep to skip searching these files (mostly JPEG and PNG images). In the directories are also many binary files which match "foo=". It’s on a common Linux machine, I have bash shell: grep -ircl "foo=" * To display only the lines that do not match a search pattern, use the -v(or –invert-match) option.I’m looking for the string foo= in text files in a directory tree. We can avoid this in two ways: Adding 1d command after 1p. If specified pattern matches also first line, it will be printed twice (once by p command and once because of a match). As mentioned in comments, there is a problem with this approach. Rest of the lines are printed (so only lines that do match the pattern). To ignore the case when searching, invoke grep with the -i option. This means that the uppercase and lowercase characters are treated as distinct. The -w option tells grep to return only those lines where the specified string is a whole word (enclosed by non-word characters). Special characters are the regular expressions used in commands to perform several actions like #, %, *, &, $, etc. Grep can identify the text lines in it and decide further to apply different actions which include recursive function or inverse the search and display the line number as output etc. It is used for searching in more than one file. For example, to print the lines that do not contain the string nologinyou would use: grep -wv nologin /etc/passwd root:x:0:0:root:/root:/bin/bash How are special characters used in the grep command? To display only the lines that do not match a search pattern, use the -v(or –invert-match) option.
