一个使locate更好用的脚本

Mylocate is an enhancement to locate .
Locate always find thousands of  files which always make me crazy . So I decided to write a wrapper to make locate looks more cute.
e.g.
     $ ./mylocate.sh  -d 3 -k beatles
        dirdepth=3
        keyword=beatles
        142 /home/jldev/music
     $ ./mylocate.sh  -d 4 -k beatles
        dirdepth=4
        keyword=beatles
        25 /home/jldev/music/beatles.6
        25 /home/jldev/music/beatles.3
        25 /home/jldev/music/beatles.2
        25 /home/jldev/music/beatles.1
        24 /home/jldev/music/beatles.5
        18 /home/jldev/music/beatles.4
EOF

}

locatem() {
        locate -i -r  "$keyword"|sed "s;^\(\(/[^/]*\)\{$dirdepth,$dirdepth\}\).*$;
\1;"|awk '{if ($0 in p) {p[$0]++} else {p[$0]=1}}END{ for (i in p) print p,i;}'
|sort -n -r|more
}

while getopts "d:k:" OPT
do
        case $OPT in
        d) dirdepth="$OPTARG"; echo "dirdepth=$dirdepth" ;;
        k) keyword="$OPTARG"; echo "keyword=$keyword" ;;
        esac
done

for i in dirdepth keyword ;do
        (set|grep "^$i=" 1>/dev/null) || { usage; exit 66; }
done
