How to take backup of modified files

[yogesh kumar_2]

Hi,
I have one script in my machine,so if i run that script means it will display only modified files.The following format is shown below.

M /te/yogesh/stm/trs/as/xxx.cpp
M /te/yogesh/foundation/trs/as/xxx.isd
M /te/rajesh/turbo/rim/xxx.h
M /te/rajesh/turbo/misc/xxx.h

So the above modified files(i,e with absolute path)i am getting.So i want to copy those modified files with that absolute path in to my destination path (i,e/net/cse-ben/backup)

Can any one tell me how to do scripting in this issue.So that it will be helpful for my script.

Hi choudary,

Suppose if i want to take modified files from /ae directory.What command i have to execute.

[Sandeep_Chaudhary]

find /ae -mtime +1 -print | cpio -ov > /net/cse-ben/backup/tree.cpio

[yogesh kumar_2]

Its showing following error

Truncating inode number
/ae
1 block

[Sandeep_Chaudhary]

create an archive with:

find /ae +mtime +1 -print|cpio -ovcBO

restore archive with

cpio -ivcI

-c option should avoid this error

Hi first i checked the modified files.I use the following commands.

find /ae .mtime +1 print | more

But it is displaying each and every files inside that /ae directory

[Sandeep_Chaudhary]

man find


-mtime n True if the file modification time subtracted
from the initialization time is n-1 to n
multiples of 24 h. The initialization time
shall be a time between the invocation of the
find utility and the first access by that
invocation of the find utility to any file
specified in its path operands.

+1,-1,1=what does it mean

Hi,

no need for an additional find, when you have the file list already!
Just drop the leading 'M /' to get a relative pathname suitable for restoring under your destination path:
cd /
sed 's:^M /::' inputfile | cpio -pdmv /net/cse-ben/backup

The 'cpio' will preserve the directory structure at the destination - for additional options see 'man cpio'.

Hi:

> +1,-1,1=what does it mean

See the manpages for 'find'. '+n' means more than 'n'. '-n' means less than 'n'; and 'n' means exactly 'n'. In this case, 'n' is in the units of one day (measured as 24-hours).
