Hi,
This silly script brings grep into trouble, please don't ask why I do this that way (and yes, I know here-docs ...):
<<<SSSCCCRRRIIIPPPTTT>>>
#!/bin/sh
extract () {
grep -m 1 -A 99 '^//START '$1'$' $0 | \
grep -m 1 -B 99 '^//STOP '$1'$' | \
grep -v '^//\(START\|STOP\) '$1'$'
}
extract /etc/rc.local >rc.local
extract /etc/rc.conf >rc.conf
exit
//START /etc/rc.local
hier config fuer neues system
da auch config fuer neues system
//STOP /etc/rc.local
//START /etc/rc.conf
hostname="blub.hausen"
//STOP /etc/rc.conf
<<<///SSSCCCRRRIIIPPPTTT>>>
Here is the backtrace:
<<<GGGDDDBBB>>>
(gdb) bt
