I have a rc.local script that runs fine in csh, but I'd like to change it to sh, but I've had no success at it.

the simplest conversion to sh (with some fixes*) would be something like:
#!/bin/sh if $(ping -w 1 -c 1 -n 192.168.1.3 | grep -q "1 packets") ; then mount /nfs/bulk2 fi
bash only. (ie, #!/bin/bash)
Incorrect. $() is POSIX: http://pubs.opengroup.org/onlinepubs/9699919799/utilities/V3_chap02.html#tag...
Um, no, as I've said before, $() is a bashism. Yes it is neater, but try running that on HP-UX and see how well you go.
Granted, only because HP-UX doesn't necessarily implement current POSIX. -- Regards, Matthew Cengia
