Replacing "// " with ";" using sed
Comment
1 / 1
In the sed
command, you can use the substitute (s
) command to replace occurrences of "// " with ";". Here's how you can do it:
bashsed 's#// #;#g' input_file > output_file
In this command:
s
: Indicates the substitute command insed
.#
: Delimiter used to separate the pattern to be replaced and the replacement string. We use#
as the delimiter to avoid conflicts with the forward slashes in the pattern.//
: The pattern to be replaced. Here, we are looking for occurrences of "// " in the input file.;
: The replacement string. We want to replace "// " with ";".g
: Theg
flag at the end of thesed
command means "global," which ensures that all occurrences of the pattern in each line are replaced, not just the first occurrence.
The sed
command reads from the input_file
, performs the replacement, and writes the modified content to the output_file
.
Example:
Suppose you have a file named input.txt
with the following content:
arduinoThis is a test // with some comments.
Another line // with comments.
After running the sed
command, the output.txt
will contain:
csharpThis is a test ;with some comments.
Another line ;with comments.
The occurrences of "// " have been replaced with ";" in the output.txt
file.
