grep.md

Grep AND pattern

Searches inside a filesystem a file with term1 AND term2 strings inside it (in this order)

find . |grep -i -e 'term1.*term2'

Multiple grep in the same command

# Exclude from ls command: file1,file2
ls -la | grep -v -e file1 -e file2

Seek 'n' Destroy

Massive search and replace a string inside a bunch of files, it might take some time...

grep -rIl 'Some Text Here' /path/where/files/are/* | xargs sed -i 's/Some Text Here/Ben is cool/g'

Grep content from a line and print N lines after it

In this example I'm searching This Pattern in filename and it prints up to 20 lines after it

grep -A 20 "This Pattern" /path/to/filename
