Try this:

Code:
OLDEST=$(ls -rt1 *.segd | head -1)
SECS=$(date -r $OLDEST +%s)

ls -rt1 *.segd | while read file
do
    let SECS=SECS+60
    touch -t $(date -d @$SECS +%Y%m%d%H%M) "$file"
done

It is working fine,, Thanks a lot..

I notice that your scrip take the date and time for the fist file.

How I can assign a specific date entered manually... for the first file ,, can be a variable.. For example ..

And then your scrip will take this date and make the process...For example .. I will like to start on Feb 08 06:00 and then next file shoulbe Feb 08 06:01.... ...

The main point in this case is that I need to change the time and date stamp, using a old date an time.

Your help is really appreciated.

I got it like this:

Code:
#!/bin/bash

touch -t 1302080500.00 *.*
                      
OLDEST=$(ls -t1 *.segd | head -1)
SECS=$(date -r $OLDEST +%s)

ls -t1 *.segd | while read file
do
    let SECS=SECS+60
    touch -t $(date -d @$SECS +%Y%m%d%H%M) "$file"
done

Thanks for your help

I fix it as following

Code:
#!/bin/bash

tape=$1
p1=$2 # Motnh
p2=$3 # Day
p3=$4 # Hour
p4=$5 # Min

cd /mnt/data1/SEGD/tape"$tape"

touch -t 13"$p1""$p2""$p3""$p4".00 *.*
                      
OLDEST=$(ls -t1 *.segd | head -1)
SECS=$(date -r $OLDEST +%s)

ls -t1 *.segd | while read file
do
    let SECS=SECS+60
    touch -t $(date -d @$SECS +%Y%m%d%H%M) "$file"
done

usage: fix_timestamps 2984 02 08 00 00

Thanks

Yes your solution looks fine, you can improve performance by just using the passed param to set the SECS var like this:

Code:
tape=$1

if [ $# -eg 2 ]
then
    SECS=$(date -d "$2" +%s)
else
    SECS=$(date -d "$2/$3 ${4:-00}:${5:-00}" +%s)
fi

cd /mnt/data1/SEGD/tape"$tape"

for file in *.segd
do
    let SECS=SECS+60
    touch -t $(date -d @$SECS +%Y%m%d%H%M) "$file"
done

Usage:

fix_timestamps tape datestr
fix_timestamps tape month day [hour [min]]>

eg:
Code:
fix_timestamps 7593 02 08
fix_timestamps 7590 02 08 14 51
fix_timestamps 7592 "last tuesday"
fix_timestamps 7592 "today -3 days"
fix_timestamps 7592 "Feb 16 2008"
