Add Date

mccoubreyr · #1 (**permalink**) 01-19-2004

I have a file with date and time in it YYYYMMDDHHMISS

cat payt_date.dat
20031007201031

and I need to add 10minutes

Any ideas?

Is this what you want? If not, explain more about what you're trying to do...

sed 's/20031007201031/20031007202031/g' payt_date.dat

the date field could be any date/time , I need a shell that works out the date + 10 minutes . I should have explained this.

The shell is not the best tool for date/time arithmetic. Assuming you have perl...

Code:

#!/usr/bin/ksh
touch -t $(sed 's/\(..\)$/.\1/' payt_date.dat) payt_date.dat
perl -e '
  ($dev,$ino,$mode,$nlink,$uid,$gid,$rdev,$size,
    $atime,$mtime,$ctime,$blksize,$blocks)=stat("payt_date.dat");
  ($ss,$mm,$hh,$DD,$MM,$YY)=localtime($mtime+600);
  printf "%04d%02d%02d%02d%02d%2d\n",$YY+1900,$MM+1,$DD,$hh,$mm,$ss;
' > payt_date_plus_ten.dat

cat payt_date_plus_ten.dat
20031007202031
