SED command failing while substituting variable with error unterminated `s' command

vnarvankar · 03-10-2016, 04:07 AM

I am trying to run sed from script to replace a value in a string with a variable.
cat FileLoad.template | sed -e "s#<<SID>>#$v_sid#g" > FileLoad.ctl

This FileLoad.template contains the string <<SID>> and it should be replaced with value in v_sid. Value in v_sid is A145_20120348. While substituting with this value it failing with error unterminated `s' command. Can anyone suggest what is wrong in this command?

While written in a vastly different manner from how I'd do this, the sed command you've written should work. I'm guessing this depends upon the environment from which you're running. I have BASH for my shell.

A suggestion to try:

Code:

/bin/sed -e s/<<SID>>/$v_sid/g FileLoad.template > FileLoad.ctl

Another suggestion to try:

Code:

/bin/sed -e s/\<\<SID\>\>/$v_sid/g FileLoad.template > FileLoad.ctl

Works fine for me. Try using "set -x" so that you can see what arguments the shell is actually passing to the sed command.

BTW, this is one of those "useless use of cat" occasions. The sed command is perfectly able to read that file itself.
