strcmp
Set $varname to strcmp(s1, s2)
General form
strcmp variable string1 string2
Compare two strings and set the variable named to the result: negative if string1 sorts before string2, 0 if they are the same, and positive if it sorts after. Quotes around the strings are removed first. This is useful in command scripts, with if.
Example
strcmp res "abc" "abd" echo $res set mode = fast strcmp same $mode fast if $same = 0 echo fast mode end
The first echo prints -1.
