"sed" Insert Backslash to File
Comment
1 / 1
You can use the sed
command to insert a backslash at the beginning of each line in a file. Here's how you can do it:
bashsed -i 's/^/\\/' yourfile.txt
This command uses the regular expression ^
to match the beginning of each line in the file and replaces it with a backslash.
Explanation of the command components:
-i
: This flag tellssed
to edit the file in-place.'s/^/\\/
': This is the substitution command. It searches for the beginning of each line (^
) and replaces it with a backslash (escaped as\\
).
Replace yourfile.txt
with the name of the file you want to modify. Make sure to create a backup of the file before running this command in case you need to revert the changes.
