When using the Grep command to find a search string in a set of files, is there a way to dump the results
to a text file?
Also is there a switch for the Grep command that provides cleaner results for better readability,
such as a line feed between each entry?
Perhaps there is a Grep script that outputs cleaner results
Thanks
The output of grep and other commands can be saved to a file by using a greater-than '>' symbol to redirect the standard output stream. Try something like...
grep "some pattern" some-file-to-search.txt > the-results.txt
To double space the resulting file, you might want to try 'sed', the steam editor. See if this works...
sed G your-file.txt
I like to use 'tee' to print the results to the console AND to a file. Also, the "--color=auto" option to grep can help with readability of output, but I'm not sure how well it works in all shells when reading the results from a text file. Try something like this:
grep --color=auto "pattern" /path/to/file.txt | tee -a logfile.txt
I like the idea of using sed to double-space, but you can accomplish the same thing (grep + sed G) in one line of awk:
awk '/pattern/ {print $0 "\n"}' /path/to/file.txt
I hope this helps!
-G
...but you can accomplish the same thing (grep + sed G) in one line of awk
True, but piping the output to sed makes it pretty trivial...
grep "some pattern" some-file.txt | sed G
Right! There's nothing wrong with it, I just have a personal bias against pipes ;)
