Please use code tags for code snippet and quote tags for text input/output.

Example i gave is for file and it refers to line such as first , exclude last line.

Code:
sed -e '1{n};$!s/./&I/10' line

is wrong here.

Is below are contents of file or file names ?

Quote:
XXXXXXXXXXXXXXXXXXXXXXXXXXXXX 293800206774 XXXXXXXXXXXXXXXXX
10210496781000100293800206774 % 30095 15962835
10210496781000100293800206774 $ 34099 17054579
10210496781000100293800206774 # 999 00000000
Here is what i can simulate with multiple files:

Code:
ls 
123.txt  456.txt  f1  f2

Code:
for file in *.txt
do
echo "File Name=" $file
sed '1{n};$!s/./&a/10' $file
done

Gives output :
Quote:
File Name= 123.txt
1234567890ABCD
1234567890aXYZ
1234567890aPQR
1234567890LMN
File Name= 456.txt
1234567890ccc
1234567890abbb
1234567890addd
1234567890eee
Once you are sure that this is what you want, you can use in-place edit option
Code:
-i

to update in the file itself. Please note , you can not undo .

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
