-I {}Placeholder — insert each arg at {} in the command -P NRun N commands in parallel -n NPass N arguments at a time -0Null-delimited input (safe for filenames with spaces) -tPrint each command before running (debug mode) -rDon't run command if input is empty

$ find . -name "*.tmp" -print0 | xargs -0 rm -f

# Deletes every .tmp file — -print0/-0 handles spaces in names

Null delimiter is the safe way to handle filenames

$ cat urls.txt | xargs -P4 -I{} curl -sO {}

# Downloads all URLs 4 at a time, in parallel

-P4 runs 4 curl processes simultaneously — massive speedup

$ find . -name "*.log" | xargs -I{} mv {} archive/

archive/app.log archive/error.log archive/access.log
