all,

i have create a script
Code:
#!/bin/sh
 DATE="`date +%d`_`date +%m`_`date +%y`_`date +%H`_`date +%M`_`date +%S`.log"
 ls -lrt *.log | awk '{f=$NF};END{print f}' > latestfile.tmp
 awk 'BEGIN { RS = "" ; FS = "\n" } ; { print $2 ",changeme," $4 }' *.csv > result.tmp
 latesta=$(/bin/cat latestfile.tmp)
 awk 'BEGIN { RS = "" ; FS = "\n"} ; { print $2 }' $latesta  > mytime.tmp
 latestb=$(/bin/cat mytime.tmp)
 sed -e "s/changeme/$latestb/g" result.tmp > final.tmp
 mv final.tmp $DATE

but it give me an error for sed command:

Code:
sed: -e expression #1, char 17: unknown option to `s'

UPDATE: i just found out that it because i "changeme" with "08/10/2012,4:11 PM"

so what is the proper way to change "changeme" with "08/10/2012,4:11 PM" ?

thank you

The variable latestb must be containing "/" characters. This is confusing sed as you have used "/" as the delimiters for s, pattern, replacement and flags. Try:
Code:
sed -e "s:changeme:$latestb:g" result.tmp > final.tmp

now my homework is how to modify time format from 12 Hours to 24 Hours
Code:
from : 08/10/2012,4:11 PM
to 08/10/2012,16:11

Try
Code:
awk 'BEGIN {FS="[/,: ]"}; $6=="PM" {$4=$4+12; $6=""} {print $1"/"$2"/"$3","$4":"$5}'

There may be better ways to produce the output format...
