question about variables with sed
Hi,
I am trying to do some mass replacements in lots of scripts, and using sed. However sed doesn't seem to like to be able to dereference variables within the substitute clause. For example: tab=newtable cat f1 | sed 's/oldtable/$tab/g' doesn't work. it would replace oldtable with the literal ( $tab ). I've tried quoting out the $, using eval etc.. but nothing seems to work. Any ideas are appreciated. Thanks, floyd |
