Search for PATTERNS in each FILE. Example: grep -i 'hello world' menu.h main.c PATTERNS can contain multiple patterns separated by newlines. Pattern selection and interpretation: -E, --extended-regexp PATTERNS are extended regular expressions -F, --fixed-strings PATTERNS are strings -G, --...
1. Use fgrep for Fixed Strings Accelerate searches without regex: fgrep -r "static_string" /dir 2. Limit Context Lines Avoid bloating output with -m to cap matches: grep -m 50 "pattern" large_file.txt 3. Parallel Processing with xargs ...
Example 2: Apply grep & grepl with Multiple PatternsWe can also use grep and grepl to check for multiple character patterns in our vector of character strings. We simply need to insert an |-operator between the patterns we want to search for....
