I need to sort a file based on the number of chars in the first column.I have no idea on how to go about this. (On Linux, so sed/awk/sort is available).An example:.abs is bla bla 12.abc is bla se 23 bla.fe is bla bla bla.jpg is pic extension.se is for swedish domainswhat I want is to sort these lines, based on the length of the first column in each line.Some of the lines start with 4 characters, some start with 3, or 2. I want the result to be something like:.fe is bla bla bla.se is for swedish domains.abs is bla bla 12.abc is bla se 23 bla.jpg is pic extensionIs this even possible?
