xargs grep 'texttofind' The above command is fine if you don’t have many files to search though, but it will search all files types, including binaries, so may be very slow. Therefore, the output highlights the following results: if.
The result shows all instances where the letter i appears followed by an f in the. The regex searches for the character string. If you don't have find, it gets complicated. bbuffer.h code, Bounded Buffer implementation to manage open files that supports multiple readers but only a single writer. Recursive grep on Unix without GNU grep If you do not have GNU grep on your Unix system, you can still grep recursively, by combining the find command with grep: find. Run the following command to test how grep regex works: grep if. If there are many files, you can use a for loop over all the files (still ash-only because of the command substitution). ash and not hush), and there aren't too many files to consider, you can generate the list of file names with find and pass that as an argument to grep. If you have find but it doesn't have -exec, and your file names are tame (no newlines or \[*?), and your shell supports command substitutions (i.e. The tutorial also explains the recursive search with and without the directory paths given in the grep command. The grep command has used many flags to work differently while doing a recursive search, i.e., -r and include. If you have no suitable xargs, you'll need to invoke grep on each file name separately: find /some/dir -type f -exec grep -H PATTERN \ The recursive search has been demonstrated within this guide using the Grep command. If your file names are tame (no whitespace or \'"), you don't need -print0/ -0: find /some/dir -type f |xargs grep -H PATTERN
Recursive grep install#
I can't install Cygwin, or any 3rd party tools like UnxUtils on this server unfortunately.
Recursive grep windows#
print xargs grep -i 'string' I'm stuck with just cmd.exe, so I only have Windows built-in commands. Here's the recursive search I performed in the previous example to do a grep search in the current folder: grep -r simple. With this option, grep will look into all the files in the current (or specified) directory and it will also look into all the files of all the subdirectories. print or the more-preferred method: find. Grep provides a -r option for the recursive search. Note that if no file operand is given, grep searches the working directory. I need to do a recursive grep in Windows, something like this in Unix/Linux: grep -i 'string' find. If support for -print0 and -0 are compiled in, then you can use xargs to invoke grep for many files at once¹: find /some/dir -type f -print0 | xargs -0 grep -H PATTERN With grep utility we have two arguments which can help you perform grep recursively, from the man page of grep Advertisement -r, -recursive Read all files under each directory, recursively, following symbolic links only if they are on the command line. Combine find to traverse directories recursively with grep.
