Every new command is wrapped in a tweet and posted to Twitter. Following the stream is a great way of staying abreast of the latest commands. For the more discerning, there are Twitter accounts for commands that get a minimum of 3 and 10 votes - that way only the great commands get tweeted.

Are the two lines anagrams?

Terminal - Are the two lines anagrams?
anagram(){ s(){ sed 's/./\n\0/g'<<<$1|sort;};cmp -s <(s $1) <(s $2)||echo -n "not ";echo anagram; }; anagram foobar farboo;

Are the two lines anagrams?

This is just a slight alternative that wraps all of #7917 in a function that can be executed

Are the two lines anagrams?

This works by reading in two lines of input, turning each into a list of one-character matches that are sorted and compared.

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 :-)

Know a better way?

If you can do better, submit your command here.

What others think

I would change that $1 in the s function to "$@" so that you can compare strings with spaces in them. I would also convert the strings to lowercase and strip any whitespace since neither should have any bearing on whether the strings are anagrams.

anagram(){ s(){ sed 's/[[:space:]]*//g;s/./\n\0/g'<<<"$@"|tr A-Z a-z|sort;};cmp -s <(s $1) <(s $2)||echo -n "not ";echo anagram; }
