To double the number of backslashes in a string using awk
, you can use one of the following commands:
gsub
function:echo "this is\\a string\\with backslashes" | awk '{gsub(/\\/,"\\\\")};1'
Output:
this is\\a string\\with backslashes
gensub
function:echo "this is\\a string\\with backslashes" | awk '{print gensub(/\\/,"\\\\\\","g")}'
Output:
this is\\a string\\with backslashes
sub
function:echo "this is\\a string\\with backslashes" | awk '{sub(/\\/,"\\\\")}1'
Output:
this is\\a string\\with backslashes
All of these commands use regular expressions to match a single backslash and replace it with two backslashes. The gsub
and gensub
functions replace all occurrences of the pattern, while the sub
function replaces only the first occurrence.
