AWK split string then deliminate it as well -

need splitting below.

100gb@sdb,100gb@sdc 

into this

sdb sdc 

everything i've tried keeps giving me

sdb 100gb 

for arbitrary number of disks, try:

$ echo '100gb@sdb,100gb@sdc,10kb@sdd' | awk -f'[@,]' '{for (i=2;i<=nf;i+=2) printf "%s ",$i; print ""}' sdb sdc sdd  

answers original question

using awk

$ echo '100gb@sdb,100gb@sdc' | awk -f'[@,]' '{print $2,$4}' sdb sdc 

using sed

$ echo '100gb@sdb,100gb@sdc' | sed 's/^[^@]*@//; s/,[^@]*@/ /' sdb sdc 

using bash

$ s='100gb@sdb,100gb@sdc'; s=${s#*@}; echo ${s/,*@/ } sdb sdc
