실행시 에러남.

sudo apt install dbus-x11

Adding the line

NO_AT_BRIDGE=1

to /etc/environment (or export NO_AT_BRIDGE=1 on console) solved the problem for me.

if [ -z '$1' ]; then
echo input words
exit 0
fi

PATTERN=$1

grep --color=auto -rwnI --exclude='tags' --exclude='cscope.out' --exclude='.depend' --exclude='.html' --exclude-dir='.svn' "${PATTERN}" .
