#8 psp for any UNIX system, my own "service" script Posted by khopesh (129.10.xx.xx) on Thu 21 Feb 2008 at 21:27 I've had a similar script for a long while. It works on older UNIX systems that lack pgrep and bash, and it figures out which type of "ps" program is installed. However, it will not hide the grep line if you are using a regex that ends in a special character: (from a file sourced by .profile) [ `uname -s` = SunOS ] && [ -x /usr/ucb/ps ] && alias ps=/usr/ucb/ps if ps auxww >/dev/null 2>&1 # works in linux + bsd (and solaris w/ ucb's ps) then alias psax='ps auxww' else alias psax='ps -ef' fi psl() { local grep=grep start end type egrep >/dev/null 2>&1 && grep=egrep psax |head -n1 |GREP_COLOR="1;38" $grep . # bold header if [ $# = 0 ] then psax else start="${*%[!]?*+.)$]}" # cut off last character if its not special end="${*#$start}" # get just that last character (if !special) psax |$grep -i "$start${end:+[$end]}" # search for args if present fi } For my /usr/local/bin/service script, I use the following. Note that the return value isn't screwed up by my error message hack. If you don't trust those last two lines, use "$RC" "$@" instead. #!/bin/sh RC="/etc/init.d/$1" case $1 in # if we're approximating redhat, httpd == apache(2) http*|apache*) [ ! -x "$RC" ] && RC="/etc/init.d/apache2" ;; esac if [ ! -x "$RC" ]; then if [ "$1" = "-list" ] || [ "$1" = "--list" ]; then cd /etc/init.d find * -type f -perm -u+x \ |egrep -v '^(skeleton|.*\.dpkg|rc|single|reboot|halt|bootclean)' \ |xargs ls exit 0 fi echo "Invalid service: '$1'" >&2 echo "You can get a list of services with '`basename $0` --list'" >&2 echo "Get further help with '`basename $0` SERVICE help'" >&2 exit 1 fi shift # here's a clever hack where we safely change the "Usage: ..." statement exec 3>&1 exit `(("$RC" "$@" 4>&-; echo $? >&4)|sed 's:/etc/init.d/:service :' 1>&3) 4>&1`
