Are the two lines anagrams?

s(){ sed 's/./\n\0/g'<<<$1|sort;};cmp -s <(s foobar) <(s farboo)||echo -n "not ";echo anagram
Are the two strings anagrams of one another? sed splits up the strings into one character per line the result is sorted cmp compares the results Note: This is not pretty. I just wanted to see if I could do it in bash. Note: It uses fewer characters than the perl version :-)

What Others Think

You are using sed, two forks and two named pipes. That's a waste. You can just iterate from the beginning of str1 and from the end of str2 and compare values.

Yes, but I was going for concise, not pretty -- just aiming to undercut the perl version. Give us an example and show us what you mean :-)

What do you think?

Any thoughts on this command? Does it work on your machine? Can you do the same thing with only 14 characters?
