This should be easy: I want to run sed against a literal string, not an input file. If you wonder why, it is to, for example edit values stored in variables, not necessarily text data.
When I do:
sed 's/,/','/g' "A,B,C"
where A,B,C is the literal which I want to change to A','B','C
I get
Can't open A,B,C
As though it thinks A,B,C is a file.
I tried piping it to echo:
echo "A,B,C" | sed 's/,/','/g'
I get a prompt.
What is the right way to do it?
You have a single quotes conflict, so use:
echo "A,B,C" | sed "s/,/','/g"
If using bash, you can do too (<<< is a here-string):
sed "s/,/','/g" <<< "A,B,C"
but not
sed "s/,/','/g" "A,B,C"
because sed expect file(s) as argument(s)
EDIT:
if you use ksh or any other ones :
echo string | sed ...
Works like you want:
echo "A,B,C" | sed s/,/\',\'/g
My version using variables in a bash script:
Find any backslashes and replace with forward slashes:
input="This has a backslash \\"
output=$(echo "$input" | sed 's,\\,/,g')
echo "$output"
