Like -wholename, but the match is case insensitive. Like -regex, but the match is case insensitive. This test returns false unless the symbolic link is broken. If the -L option or the -follow option is in effect, Like -lname, but the match is case insensitive. The Linux find command has several more case-insensitive operators, including these, which I'm taking directly from the find command man page: The -iname option is what makes the search case-insensitive. The key to that case-insensitive search is the use of the -iname option, which is only one character different from the -name option.

You can silence the stderr output by adding 2>/dev/null to the end of your command. ![]() Note that on some systems you may also have to use the -print option at the end of that command, like this:įind. 5 Answers Sorted by: 72 Those warnings are directed to the stderr stream, as opposed to the standard out file descriptor. (FWIW, I add the -type f option to tell find to just look for files, and not directories.) Here is a small script, which I've called pgrepdiff, which will allow you to use a PCRE to match your diff output. echo SOME grep -P ' (i)some' SOME Unfortunately this flag is not available in grepdiff and, as far as I can see, neither is -i (case insensitive match). Here's how I did a case-insensitive search trying to find the same typeahead files with the find command: 1 Answer Sorted by: 2 You need to tell the grep family to use Perl-like REs. If for some reason you can't find your files with the Linux locate command, or your system doesn't have the locate command installed, you can also try searching with the traditional Unix find command. To search my entire filesystem for files and directories that contain the string typeahead, just use this command:Ĭase-insensitive file searching with the find command l Display names of files with matching lines -i Ignore case -v Match lines. It's easy to perform a case-insensitive file search with the Linux locate command: just add the -i flag. The grep command is perfect in these situations and we explore some of its. ![]() Case-insensitive file searching with the locate command Both the find command and the locate command have command-line options that provide this support. I was happy to learn that both of my favorite Unix and Linux file-finding utilities support case-insensitive file searching. While trying to remember where I put it I realized I was going to have to do some case-insensitive file searching. ![]() Taking patterns from a file (-f): we can place all patterns in a separate file, one pattern per lin.Earlier today someone asked for the source code for my TypeAhead predictive-text, type-ahead, auto-complete JNLP Swing application. > grep âe âAgarwalâ âe âaggarwalâ âe âagarwalâ emp.lst Grep Ignore Case You can add an -i or ignore-case flag to make grep case sensitive: grep -i command line textfile.txt grep ignore-case command line textfile.txt Running Through an Example 1. Matching Multiple Patterns(-e): With the âe option, you can match the three agarwals by using grep like this: CoMMand LiNe To clarify, if my file contained the string command line, none of the above searches would return anything. > Grep âv âdirectorâ emp.lst > other listÄisplaying line Numbers (-n): The ân(number) options displays the line numbers containing the pattern, along with the lines:Ĭounting Line Containing patterns (-c): The âc (count) option counts the number of lines containing the pattern ( which is not the same as number of occurrences).Äisplaying Filenames (-l): The âl (list) option displays only the files names of files containing the pattern. Usage grep patternThus, you can create a file other list containing all but director. Deleting Lines or Inverse(-v): -v (inverse) option selects all except lines containing the pattern. inline-codeignore-case.inline-code flag to make grep case sensitive.
