define a function for searching bash history

hgrep() { ... } longer then 255 characters, see below
hgrep() { if [[ ${#} -eq 0 ]] then printf "usage:\nhgrep [--nonum | -N | -n | --all-nonum | -an | -na] STRING\n" return 1 fi while [[ ${#} -gt 0 ]] do case ${1} in --nonum | -N | -n | --all-nonum | -an | -na) builtin history | sed 's/^[[:blank:]]\+[[:digit:]]\{1,5\}[[:blank:]]\{2\}//' | grep -iE "(${*:2})" break ;; *) builtin history | grep -iE "(${*})" break ;; esac done } 'hgrep -n' helps in using full grep support, e.g. search for _beginning_ of specific commands, see example output
Sample Output
$ hgrep -n '^diff'
diff foo.txt bar.txt
