1) Word split /proc/cmdline into an array and use in_array from /etc/rc.d/functions:

2) Word split /proc/cmdline with printf and use grep -x:

if printf "%s\n" $(

These look very strange. I would be more tempted to inline the in_array and say:

/bin/dmesg -n 3 for cmdlinearg do     [[ $cmdlinearg == "verbose" ]] && /bin/dmesg -n 8 done

which seems more readable and less magical to me.

Rémy.

Sure, also valid. It occurred to me that the array isn't actually necessary, as you can just word split in passing to in_array but inlining here is fine too.

one minor nit to pick with the innards of your loop...

 [[ $arg = "verbose" ]] && { /bin/dmesg -n 8; break; }

p.s. particularly as of late, I've found that "readable" is highly subjective, particularly when it comes to Bash.

I propose two patches (mutualy exclusive), taking code from dave and remy.

PS: Thomas, i (currently) cannot send patch directly from my git. Gonna happen.

Sorry, little mistake in previous one. -- Sébastien Luttringer www.seblu.net
