Finding all files containing a text string on Linux

Finding all files containing a text string on Linux

Do the following:

grep -rnw '/path/to/somewhere/' -e "pattern"

-r or -R is recursive, -n is line number and -w stands match the whole word. -l (lower-case L) can be added to just give the file name of matching files.

PSQL

Magic words:

psql -U postgres

If run with -E flag, it will describe the underlaying queries of the \ commands (cool for learning!).

Most \d commands support additional param of __schema__.name__ and accept wildcards like *.*
