How to use sed when a match has forward slashes
I'm trying to replace an alias with its match using sed but the match contains forward slashs so it causes the sed command to throw a garbled message..


cmd_list.txt sample
Quote:
PDCONFIG
AIX_myserver_1011_vintella.sudoers_cmndalias sample
Quote:
PDCONFIG=/usr/bin/pdconfig
I'm trying to use the below but like I say it throws a garbled message. Not sure what the way around this is

Code:
while read cmd_list
do
cmd_replace=$(grep -w $cmd_list AIX_myserver_1011_vintella.sudoers_cmndalias)
sed "s/${cmd_list}/${cmd_replace}/g" AIX_myserver_1011_vintella.sudoers_entries_2_A > new_out.txt
mv new_out.txt AIX_myserver_1011_vintella.sudoers_entries_2_A
done < cmd_list.txt

Code:
sed "s:${cmd_list}:${cmd_replace}:g"

try with

Code:
 
sed "s,${cmd_list},${cmd_replace},g"

Try another separator:
Code:
sed "s!${cmd_list}!${cmd_replace}!g" AIX_myserver_1011_vintella.sudoers_entries_2_A > new_out.txt

In short you can use any symbol as seperator other than / Smilie

Except for a newline or a backslash.
