identical lines (or duplicate lines from the file) (ubuntu)

Answer 1

To remove identical lines or duplicate lines from a file using a shell script in Ubuntu, you can use the sort and uniq commands.

Step-by-step explanation:

To remove identical lines or duplicate lines from a file using a shell script in Ubuntu, you can use the following steps:

1. First, you need to sort the file using the sort command. This will group identical lines together.
2. Next, you can use the uniq command with the u option to remove duplicate lines and keep only unique lines.
3. Finally, you can redirect the output to a new file to save the modified version of the input file.

An example of a shell script to accomplish this:

sort input.txt | uniq -u > output.txt-
