Ubuntu – How to search for strings inside files in a folder

software-recommendation

Is there any utility to make searches for a string inside ASCII files to avoid command line searches?

How to make a command line search, for example for the string "test" inside all files in the directory /var/x/?

You can use searchmonkey. The tool is available in the repositories, so you can simply

sudo apt-get install searchmonkey

On the other hand, command line search with grep is really intended for that...

Here is a screenshot from searchmonkey

The transcode package bundles an image stabiliser plugin vid.stab. Their video demo certainly looks convincing (if a little vomit inducing).

Ubuntu – command-line utility app which can find a specific block of lines in a text file, and replace it

This simple python script should do the task:


#!/usr/bin/env python

# Syntax: multiline-replace.py input.txt search.txt replacement.txt

import sys

inp = open(sys.argv[1]).read()
needle = open(sys.argv[2]).read()
replacement = open(sys.argv[3]).read()

sys.stdout.write(inp.replace(needle,replacement))

Like most other solutions, it has the disadvantage that the whole file is slurped into memory at once. For small text files, it should work well enough, however.
