问题
I wrote a script for a Linux bash shell.
One line takes a list of filenames and sorts them. The list looks like this:
char32.png char33.png [...] char127.png
It goes from 32 to 127.
The default sorting of ls of this list is like this
char100.png char101.png [...] char32.png char33.png [...] char99.png
Luckily, there is sort, which has the handy -V switch which sorts the list correctly (as in the first example).
Now, I have to port this script to OSX and sort in OSX is lacking the -V switch.
Do you have a clever idea of how to sort this list correctly?
回答1:
Do they all start with a fixed string (char in your example)? If so:
sort -k1.5 -n
-k1.5 means to sort on the first key (there’s only one key in your example) starting from the 5th character, which will be the first digit. -n means to sort numerically. This works on Linux too.
