Case insensitive sort

Yes I see how it works now. I actually was using a file I copied from somewhere else and the -k3,3n only appeared to work. I was able to get the file to sort through cat file | sort -t/ -k4.15

Code:
/ifs/SQL_Backups3/SQL_SharePoint
/ifs/SQL_Backups/SQL_SharePoint1

The other question which you even mentioned is in regard to case sensitivity. Now it seems to be impossible to sort both numerically AND also disregard case, even with the f option. I've tried using different sort and uniq options and if I have a number and a word, it doesn't work. For example:
Code:
NEW
/ifs/DumpsterArchive
NEW
/ifs/data
NEW
/ifs/eas_archive
NEW
/ifs/data13
NEW
/ifs/data8
NEW
/ifs/data5
NEW
/ifs/data6
NEW
/ifs/data7

Code:
file |sort -t/ -k3.5n

works just great but even with
Code:
sort -f -t/ -k3.5n

it still puts Dumpster at the very top of the file.
I therefore tried with
Code:
 tr [a-z] [A-Z]

but as this would make all the letters upper case then it wouldn't work in the end.
So I tried sed patterns but unless the first letter was the cause of the case sensitive sort every time, I am not sure it would work.

Does sort allow the -f with the -n so that you can sort alphanumerically? If not I assume I could use some form of sed to save the pattern

irsend - basic LIRC program to send infra-red commands SYNOPSIS
irsend [options] DIRECTIVE REMOTE CODE [CODE...] DESCRIPTION
Asks the lircd daemon to send one or more CIR (Consumer Infra-Red) commands. This is intended for remote control of electronic devices such as TV boxes, HiFi sets, etc. DIRECTIVE can be: SEND_ONCE - send CODE [CODE ...] once SEND_START - start repeating CODE SEND_STOP - stop repeating CODE LIST - list configured remote items SET_TRANSMITTERS - set transmitters NUM [NUM ...] SIMULATE - simulate IR event REMOTE is the name of a remote, as described in the lircd configuration file. CODE is the name of a remote control key of REMOTE, as it appears in the lircd configuration file. NUM is the transmitter number of the hardware device. For the LIST DIRECTIVE, REMOTE and/or CODE can be empty: LIST "" "" - list all configured remote names LIST REMOTE "" - list all codes of REMOTE LIST REMOTE CODE - list only CODE of REMOTE The SIMULATE command only works if it has been explicitly enabled in lircd. -h --help display usage summary -v --version display version -d --device use given lircd socket [/var/run/lirc/lircd] -a --address=host[:port] connect to lircd at this address -# --count=n send command n times EXAMPLES
