Linux – How to filter out unique results from grep output

command linelinuxUbuntu

In linux, I can grep a string from a file using grep mySearchString myFile.txt.
How can I only get the result which are unique?

Best Answer

You can achieve this with the sort and uniq utilities.

example:

[john@awesome ~]$ echo -e "test\ntest\ntest\nanother test\ntest"
test
test
test
another test
test
[john@awesome ~]$ echo -e "test\ntest\ntest\nanother test\ntest" | sort | uniq
another test
test

depending on the data you may want to utilize some of the switches as well.

Linux – When using grep from VIM, how to jump to results

When you press ENTER, you should be looking at line 3 of file1.txt. To jump to the next match, execute :cn; to jump to the previous match, execute :cp. Executing :copen will open a window containing the list of matches. Move the cursor to the desired match and press ENTER to jump to that match.

For more on using :grep, see

:help grep
:help quickfix.txt

Typing :cn and :cp to move forward and backward in the quickfix list can be awkward, so I use these mappings:

nmap <silent> <C-N> :cn<CR>zv
nmap <silent> <C-P> :cp<CR>zv

Also, the :grep command is not a plugin; it's part of Vim.

Linux – How to find file with name=“php.ini” on linux using grep command

You would normally use find not grep to find files by name.

find / -name php.ini

If you must use grep

cd /; ls -lR | grep php.ini

In both cases replace "/" with the absolute or relative path for the directory you wish to start the search in.

Note that linux also has a locate command that relies on indexing - check it's man page for details. This is fastest if the right locations are indexed.
