Replace specific line in file

Shell Programming and Scripting
1

Hello

I am working on a script where I need to replace the particular line with new line

Old line is

<outputFileNameMapping>${artifact.artifactId}-${project.version}.${artifact.extension}</outputFileNameMapping>

and new line is

<outputFileNameMapping>${artifact.artifactId}-${project.assembly.version}.${continuum.project.nextBuild.number}-Release.${artifact.extension}</outputFileNameMapping>

I tried to do it through sed command but no luck

Thanks

Show the sed script you used and what failed.

I was using the below command to do it

old_runtime_version=<outputFileNameMapping>${artifact.artifactId}-${project.version}.${artifact.extension}</outputFileNameMapping>

new_runtime_version=<outputFileNameMapping>${artifact.artifactId}-${project.assembly.version}.${continuum.project.nextBuild.number}-Release.${artifact.extension}</outputFileNameMapping>

find ${BRANCH_NAME}/A/B/pom.xml -type f -exec sed -i "s/$old_runtime_version/$new_runtime_version/g" {} \;

getting below error
sed: -e expression #1, char 114: unknown option to `s'

May I guess that there's a "/" in one of your variables?

add:

sed -i "" "s/$old_runtime_version/$new_runtime_version/g" {} \;

Both the variables has been mentioned in my above post old_runtime_version and new_runtime_version.

I tried your command and it is not working.Please suggest
