Question

I’m trying to do something in bash with sed that is proving to be extremely difficult.

I have a bash script that takes as its first argument a date.

The code want to change a line in a text file to include the passed date. Here’s the code

#!/bin/bash

cq_fname="%let outputfile="/user/cq_"$1".csv";"

sed "29s/.*/\"$ct_fname\"/" file1.sas > file2.sas

This script fails on the third line, I get something about a garbled command. Does anybody know a clever way to get this to work? How can I get a forward slash in quotes in sed?

Answer 1

You can use any character in place of the /, so just pick one that is not in $ct_fname:

sed "29s|.*|\"$ct_fname\"|" file1.sas > file2.sas
