I still can not grasp benefits of using
What's the point?
According to the man page of OS X i found in the net "-n" prevents the mv command to overwrite already existing files. That means: if you have files A, B and C and you do a
you will end up with three files again, B, C and D (the former A). Whereas, when you issue:
you will end up with only two files: B (the former A) and C. The original B will be wiped out. This may sometimes be the desired result, but sometimes it may not. To guard against accidentally wiping out a file you might want to keep is the reason "-n" exists.
i'm using SunOS 5.7 and I know theres a ls option for seeing what kind of files are in a directory. I was wondering if there was a ls option that could see if the files are txt or files that can be opened in vi (1 Reply)
How can I use the 'ps' command to view current sessions but only for a given process/user, with the -u parm?
In older versions of Unix, this used to work, but not in Sun Solaris.

fstrcmp
fstrcmp(1) General Commands Manual fstrcmp(1)NAME
fstrcmp - fuzzy comparison of strings
SYNOPSIS
fstrcmp [ -p ] first-string second-string
fstrcmp -w first-string second-string
fstrcmp -a first-file second-file
fstrcmp -s needle haystack...
fstrcmp --version
DESCRIPTION
The fstrcmp command is used to make fuzzy comparisons between strings. The "edit distance" between the strings is printed, with 0.0 mean-
ing the strings are utterly un-alike, and 1.0 meaning the strings are identical.
You may need to quote the string to insulate them from the shell.
OPTIONS
The fstrcmp command understands the following options:
-a
--files-as-bytes
This option is used to compare two files as arrays of bytes. See fmemcmp(3) for more information.
-p
--pair This option is used to compare two strings as arrays of bytes. This is the default. See fstrcmp(3) for more information.
-s
--select
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 for example.
-V
--version
This option may be used to print the version of the fstrcmp command, and then exit.
-w
--wide-pair
This option is used to compare two multi-byte character strings. See fstrcoll(3) for more information.
EXIT STATUS
The fstrcmp command exits with status 1 on any error. The fstrcmp command only exits with status 0 if there are no errors.
EXAMPLE
The fstrcmp --select option may be used in a shell script to improve error messages.
case "$action" in
start)
start
;;
stop)
stop
;;
restart)
stop
start
;;
*)
echo "$0: action "$action" unknown" 1>&2
guess=`fstrcmp --select "$action" stop start restart`
if [ "$guess" ]
then
echo "$0: did you mean "$guess" instead?" 1>&2
fi
exit 1
;;
esac
Thus, the error message frequently suggests the correct action in the face of simple finger problems on the command line.
