moin moin Mike,

when using regular expressions '$' matches the end of the line and '^'
matcheѕ the beginning of the line. So, '^$' matches a blank line.

grep -E '^fred:' /etc/passwd # shows the entry for fred's account

grep -E ':/bin/bash$' /etc/passwd # shows all of the accounts that have
bash as their shell

ciao,
