[Perl-unix-users] Pre-Dating Files Inode Modification time - howto?

[Arijit Das]

There are three type of times usually associated with a file.

1) Last File modification time

2) Last File access time

3) Last Inode Modification time.

 

It seems like the first two times can be pre-dated by using the touch command.

 

## pre-Dating to 31-Jan-2006

touch -c -t 01311200.00 core

Is there any known way to pre-date the "inode modification time"?

 

Thanks,

Arijit

 

vgamd129> touch -c -t 01311200.00 core
vgamd129> perl -e '$var = time; print $var;'

vgamd129> perl -e '$var = (stat("/remote/vtghome7/arijit/core"))[8]; print "$var\n";'

vgamd129> ls -lta core
-rw-------  1 arijit src 782336 2006-01-31 12:00 core
vgamd129> perl -e '$var = (stat("/remote/vtghome7/arijit/core"))[9]; print "$var\n";'

## Note that the "inode modification time" couldn't be pre-dated

vgamd129> perl -e '$var = (stat("/remote/vtghome7/arijit/core"))[10]; print "$var\n";'
