Shell Programming and Scripting

Hi,

I need a recursive program which when run appends todays date,month and year automatically to the existing file names..

I have aaa.txt file with some 90 odd file names.

aa.bb_cc
aa.bb_cc
.
.
.
aa.yy.zz

When the script is run for today,it should give me like..

aa.bb_cc.Mar-23-2007
aa.bb_cc.Mar-23-2007
.
.
.
aa.yy.zz..Mar-23-2007

and when the script is run for 2morrow,it should give me like

aa.bb_cc.Mar-24-2007
aa.bb_cc.Mar-24-2007
.
.
.
aa.yy.zz..Mar-24-2007

Or when the script has run for todays date,can we tell the script to automatically point to tomorrows date.Say after running Mar-23-2007,at the end it should point to Mar-24-2007.

Can anybody help me with this program....

Thanks for you help,
Kumar

Run this script once to add that days date

Code:

dt=$( date "+%b-%d-%Y" )
for i in *
do
 mv $i ${i}".${dt}"
done

Once the file has date in it use this script

Code:

dt=$( date "+%b-%d-%Y" )
for i in *
do
 mv $i ${i%.*}".${dt}"
done

If my understanding on your problem is correct, the below one will take filenames from aaa.txt and rename it with the date details..

When i execute this script..it gives me a error mesg saying...

./date.sh: syntax error at line 3: `suffix=$' unexpected

#!/usr/bin/sh

suffix=$(date+%d-%b-%y)
while read line
do
{
mv $line $line$suffix
}
done< /tmp/aaa/orig.txt

#!usr/bin/sh
#!/bin/tcsh

dt=$(date"+%b-%d-%y")

cd /tmp/aaa/

for i in *
do
mv $i ${i}".${dt}"
done

I get his error mesg when i execute the script..i dont know if i'm running it wrongly..

date1.sh: syntax error at line 4: `dt=$' unexpected

I am not finding any errors...

That code would legal on Linux but illegal on Solaris. Which is one example of why you should mention your OS. On Solaris, sh really is sh, the old Bourne shell. On Linux, sh is a link to bash. You need to switch to a modern shell like bash or ksh.
