I have a script file which I need to modify with another script to insert a text at the 8th line.

String to insert: Project_Name=sowstest, into a file called start.

I tried to use awk and sed, but my command is getting garbled.

sed awk

sed -i "" -e $'4 a\\\n''Project_Name=sowstest' $foldercc/filenames;
