fstrcmp - fuzzy comparison of strings
fstrcmp [ -p ] first-string second-string
fstrcmp -w first-string second-string
fstrcmp -a first-file second-file
fstrcmp -s needle haystack...
The fstrcmp command is used to make fuzzy comparisons between strings.
The “edit distance” between the strings is printed, with 0.0 meaning
the strings are utterly un-alike, and 1.0 meaning the strings are
You may need to quote the string to insulate them from the shell.
The fstrcmp command understands the following options:
This option is used to compare two files as arrays of bytes.
See fmemcmp(3) for more information.
--pair This option is used to compare two strings as arrays of bytes.
This is the default. See fstrcmp(3) for more information.
This option is used to select the closest needle from the
provided haystack alternatives. The most similar (single)
choice is printed. If none are particularly similar, nothing
is printed. See fstrcmp(3) for more information. See below
This option may be used to print the version of the fstrcmp
command, and then exit.
This option is used to compare two multi-byte character
strings. See fstrcoll(3) for more information.
The fstrcmp command exits with status 1 on any error. The fstrcmp
command only exits with status 0 if there are no errors.
The fstrcmp --select option may be used in a shell script to improve
case "$action" in
echo "$0: action \"$action\" unknown" 1>&2
guess=‘fstrcmp --select "$action" stop start restart‘
if [ "$guess" ]
echo "$0: did you mean \"$guess\" instead?" 1>&2
Thus, the error message frequently suggests the correct action in the
face of simple finger problems on the command line.
