s(){ sed 's/./\n\0/g'<<<$1|sort;};cmp -s <(s foobar) <(s farboo)||echo -n "not ";echo anagram

Are the two lines anagrams?

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 :-)

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