You're probably running csh or tcsh, which try and interpret the !
character even in quotes. It'll work in a script, but on the
commandline you'll need to change it to \! . Alternatively, you can
print only lines with leading spaces followed by a number with:
iostat -c 300 1 | gawk '/^ +[0-9]/ {print $1}'
