Why did this command put a whitespace at the beginning?

I have this code in a shell script:

sort input | uniq -c | sort -nr > output

The input file had no preceding white spaces, but the output does. How do I fix this? This is in bash

The default behaviour of uniq is to right-justify the frequency in a
line 7 spaces wide, then separate the frequency from the item with a
single space.

Remove the leading spaces with sed :

$ sort input | uniq -c | sort -nr | sed 's/^s*//' > output

uniq -c adds leading whitespace. E.g.

$ echo test
test
$ echo test | uniq -c
 1 test

You could add a command at the end of the pipeline to remove it. E.g.

$ echo test | uniq -c | sed 's/^s*//'
1 test
