Finding files with find
find is the Swiss Army Knife tool for quickly finding files from the command line, but its syntax is somewhat unusual. Here are some quick examples:
list all files with ls that were modified within the last 15 days:
find ./ -type f -mtime -15 | xargs ls -l
list all files whose name contains "test":
find ./ -type f -name "*test"
grep for OUR in all files modified within the last 15 days
find ./ -type f -mtime -15|xargs grep OUR
