Episode Synopsis

The 'grep' command is used to search for patterns within files.- Search for pattern within a file: grep "search pattern" path/to/file- Search for pattern using "basic" regular expressions (grep's default behavior): NOTE Supports (^, $, ., [abc], [^abc], [a-z], *, \) grep -G "search pattern" path/to/file- Interprets patterns as "extended" regular expressions: NOTE Supports (?, +, {}, (), and |) grep -E "search pattern" path/to/file- Interprets patterns as "fixed strings" rather regular expressions (disables regex): grep -F "fixed string" path/to/file- Search for a pattern in all files "recursively" in a directory: grep -r "some pattern" path/to/dir- "Ignore" binary files, search "recursively" in a directory, and print file names rather than the normal line output: grep -Irl "some pattern" path/to/dir- An inverse search for the pattern (returns lines that DO NOT contain the pattern): grep -v "some pattern" path/to/file - Search for pattern, "ignoring" case and adding line "numbers" to the output: grep -in "some pattern" path/to/file- Recursively search and do not write anything to standard output ("quiet" mode): grep -rq "some pattern" path/to/dir- Recursively search and "suppress" error messages about non-existent or unreadable files: grep -rs "some pattern" /path/to/dir- Set a "max" number of matching lines: grep -m 2 "some pattern" /path/to/fileWANT TO SUPPORT THE CHANNEL? 💰 Patreon: https://www.patreon.com/distrotube 💳 Paypal: https://www.youtube.com/redirect?event=channel_banner&redir_token=QUFFLUhqazNocEhiaGFBT1l1MnRHbnlIcHFKbXJWVnpQd3xBQ3Jtc0tsLVZJc19YeFlwZ2JqbXVOa3g0Skw4TVhTV2otNm1tM3A1bUNnamh3S2V6OGQtLTBnSjBxYTlvUXMxeEVIS3o4US10NENHMUQ3STk2a01FOFBhUnZjZFctMEhFUTg1TVctQmFfVUdxZXJ4TDl0azlYNA&q=https%3A%2F%2Fwww.paypal.com%2Fcgi-bin%2Fwebscr%3Fcmd%3D_donations%26business%3Dderek%2540distrotube%252ecom%26lc%3DUS%26item_name%3DDistroTube%26no_note%3D0%26currency_code%3DUSD%26bn%3DPP%252dDonationsBF%253abtn_donateCC_LG%252egif%253aNonHostedGuest🛍️ Amazon: https://amzn.to/2RotFFi👕 Teespring: https://teespring.com/stores/distrotubeDT ON THE WEB:🕸️ Website: http://distro.tube📁 GitLab: https://gitlab.com/dwt1 🗨️ Mastodon: https://fosstodon.org/@distrotube👫 Reddit: https://www.reddit.com/r/DistroTube/📽️ Odysee: https://odysee.com/@DistroTube:2FREE AND OPEN SOURCE SOFTWARE THAT I LIKE:🌐 Brave Browser - https://brave.com/📽️ Open Broadcaster Software: https://obsproject.com/🎬 Kdenlive: https://kdenlive.org🎨 GIMP: https://www.gimp.org/💻 VirtualBox: https://www.virtualbox.org/🗒️ Doom Emacs: https://github.com/hlissner/doom-emacsYour support is very much appreciated.
