I have a text file with many lines of text.
In Linux, how to sort the lines by their length?
You can make use of awk together with the sort program like
awk '{ print length(), $0 | "sort -n" }' /path/to/text/file
Here, we use awk to calculate the text length and sort -n to sort by the length as numbers.
If you want the original text only, you may use cut or awk again to filter away the leading number for the length.
