Find files and find files containing certain text

This is a reminder to myself as I keep forgetting how to do these basic searches in Linux.

To find files with file name containing the text foo using the command find:

## find file with "foo" in file name
find ./ -name "*foo*" ## replace ./ with path; can use shell style wildcards
## ignore upper and lower cases
find ./ -iname "*foo*"
## print pathnames of all files
find ./ -print


To find files with bar in it’s content using the command grep:

grep "bar" -r ./
## print lines without the word "bar"
grep -v "bar" -r ./
## note, can also use regexp with -E

I think it’s good practice to quote the text containing the wildcards or escape the backslashes, otherwise some shells (zsh) will perform expansion before the command even runs.
