Overview
What this command does
On Windows, "findstr" is used to search text within files. On Linux, the closest practical mapping shown here is "grep". Searches for text patterns inside files. One of the most-used Linux commands. This reference is grouped under Text Processing → Search.
Windows → Linux context
What changes when you use this on Linux?
Equivalent task, different tool
Windows findstr maps to grep for this task. Treat this as a workflow mapping rather than a character-for-character syntax translation.
Portable across the compared distros
The Debian/Ubuntu, Fedora and Arch rows use the same command in this mapping. Package availability or defaults can still vary, so check the installed tool version when an option behaves differently.
For the broader concept behind this mapping, read Linux command-line basics.

Walkthrough
Examples with explanations
# Windows: findstr "error" logfile.txt
grep "error" logfile.txt # search for 'error'
grep -i "error" logfile.txt # case-insensitive
grep -rn "TODO" ~/Projects/ # find TODOs in all files
# Super useful: pipe into grep:
ps aux | grep nginx # find nginx process
cat access.log | grep "404" # find all 404 errorsReference
Common options and variations
| Command or option | Use |
|---|---|
grep -r | Search recursively in all files |
grep -i | Case-insensitive search |
grep -n | Show line numbers |
grep -v | Show lines that do NOT match |
grep -c | Count matching lines only |
grep -l | Show only filenames that match |
Distro differences
Debian/Ubuntu vs Fedora vs Arch
Debian/Ubuntu, Fedora and Arch all use "grep" for this mapping. The command syntax shown here is portable across the three rows, although installed versions and system defaults can still vary.
| Distribution | Package manager / base | Equivalent command | Difference to notice |
|---|---|---|---|
| Debian/Ubuntu | same command | grep |
Same command on this distribution. |
| Fedora | same command | grep |
Same command on this distribution. |
| Arch | same command | grep |
Same command on this distribution. |
