The first part of the command looks for the word Walden in any files in the current directory, and the second runs another grep command on the results of the first command. I once ran into a head-scratching afternoon where sed would work with GNU extensions from the command line but not inside a shell script, and it took far too. You’d use this command: grep Walden * | grep Pond. One function that I tried, but didnt work for me was the Ignore Case checkbox. That way I can paste the results into a text file or report. One aspect that I found better than other GREP GUIs that I have tried, is that you can copy the results.

Im using it on Mac OS X 10.8.3 (Mountain Lion). Say you want to find files containing both Walden and Pondon the same line. This is a good basic GREP graphical user interface. Using the pipe ( |), a Unix redirection operator, you can tell grep to search for more than one string. (Note that you can also combine options-for instance, grep -rl Walden searches subfolders and returns only a list of files containing the word Walden. Get started with the helpful options listed here. The grep command has several options that let you fine-tune the way you search for text, as well as the kind of results grep returns. Returns the names of files containing Walden and the number of hits in each file.

I've not programmed for 2 months and maybe I'm crazy now. I am in holidays here (I'm from Argentina and it's summer here).

You might want to see what grep you are usingĪlso I guess we should ask if you are running the version of 'bash' that came with Mac OS X, or if you have installed your own bash?īy the way, Terminal, Unix, X11, and command line command, ssh, rsync, etc. I'm just trying to say that my Mac gets heavy duty use on the Unix side of the street. At work, I've been using a Mac as my workstation for 6 years, developing kernel software (in C) for Linux, Solaris, AIX, and Windows, with heavy duty bash shell and Perl scripting on the side (such as multi-thousand line scripts).

Let me explain what happens with an example: The problem is, I can't count on grep command working on OS X. I work everyday with Unix-like systems (Linux and FreeBSD), but my main system is OS X, another Unix.
