I’ve been playing around with bash scripting quite a bit recently in relation to my current job.<\/p>\n

Came up with one that’s really useful (imho) around chkconfig<\/code>:<\/p>\n

# mass set all services known to chkconfig to be `on` or `off` at given level

echo \"USAGE:\"
\necho \" $0 <level>\u00a0[on|off]\"
\necho<\/code><\/p>\n

# list all services, just the name, skip blank lines, do in order
\nSERVICES=`chkconfig --list | cut -f 1 | grep -v ^$ | grep -v ':' | sort`<\/code><\/p>\n

for SERVICE in $SERVICES
\ndo
\n\u00a0\u00a0chkconfig --level $1 $SERVICE $2
\n\u00a0\u00a0echo \"$SERVICE has been altered for $1 to state $2\"
\ndone
\n<\/code><\/p>\n

Yes – there’s an evil you could perform:<\/p>\n

for CS in `chkconfig --list | cut -f 1 | grep -v ^$ | grep -v ':'`
\ndo
\n\u00a0\u00a0chkconfig --level 12345 $CS off
\ndone
\n<\/code><\/p>\n

So, if you wanted to stop all services from coming on at startup, you could – and not know you did it until you rebooted.<\/p>\n","protected":false},"excerpt":{"rendered":"
