I wish this help you for multiple search replace check out this link
You can also use Perl which simplifies by not requiring you to backslash content:
code :
#RAND=$$;
in1="$1"
out1="$2";
#cp $3 /tmp/$3.$RAND
in=$in1 out=$out1 perl -pi -e 's/\Q$ENV{"in"}/$ENV{"out"}/g' $3

around this issue Your commands seem to work find. The problem with your sed commands is that they will just echo. You need to substitute the change in file.
code :
#!/bin/bash

env=LOCAL
ip=http://127.1.1.2:3000
if [ $env == LOCAL ]
then
   sed -i.bak 's~DOMAIN_LOCAL = .*$~DOMAIN_LOCAL = "'$ip'";~' a.txt
   sed -i.bak 's~DOMAIN = .*$~DOMAIN = '"$env"'~' a.txt
   #  Now this will make a backuo of the original file and write changes back to a.txt
else
   sed 's~DOMAIN = .*$~DOMAIN = '"$env"'~' a.txt
fi

hop of those help? git commit -m "A multi-line\n\ncommit message" will not produce a multi-line commit message anyway. The commit message will be, literally, A multi-line\n\ncommit message. Double-quotes do not cause bash to interpret printf escape-sequences.
To get a multi-line commit-message you need:
code :
git commit -m "`printf \"A multi-line\n\ncommit message\"`"

Does that help Piping is used to pass the standard output from one process to the standard error of another; you cannot pipe output directly to a variable to perform an assignment.
Instead, use command substitution:
code :
for f in "${c2[@]}"; do
    outputCheck=$(./scripts/SCRIPT_FILE.sh -v "${f}" check)
    if [[ $outputCheck != "No errors found." ]]; then
        errorNames+=("$f")
    fi
    printf '%s\n' "$outputCheck"
done
