Question

I’ve below lines in one of my startup scripts (abc.sh):

runuser root -c "export CATALINA_OPTS=\"-Xms5g -Xmx10g\"; \
    nohup $CATALINA_HOME/bin/startup.sh $CATALINA_HOME > /dev/null &"

I want to replace -Xms5g -Xmx10g with below line:

-Xms500m -Xmx1g -Xrunjdwp:transport=dt_socket,address=9000,server=y,suspend=n

I wrote a script myscript.sh which contains below code:

#!/bin/bash
sed -i~ 's/-Xms5g -Xmx10g/-Xms500m \
    -Xmx1g -Xrunjdwp:transport=dt_socket,address=9000,server=y,suspend=n' ./abc.sh

But its giving me error:

sed: -e expression #1, char 95: unterminated `s' command

Can any one help me out in correcting this command?

Note: There are other several lines as well in abc.sh

Thanks!

Answer 1

You failed to add a / at the end.

sed -i~ 's/-Xms5g\s*-Xmx10g/-Xms500m -Xmx1g \
    -Xrunjdwp:transport=dt_socket,address=9000,server=y,suspend=n/' ./abc.sh
