Top Forums Shell Programming and Scripting Adding new line at the end of file Post 302143977 by somesh_p on Monday 5th of November 2007 04:36:20 PM

Yes.. it is working fine for the files that doens't have a blank line at the end of file

But, if the file already contains a blank line at the end, the modified file is becoming zero bytes. It shouldn't modify the file, if it already has blank line at the end

Please suggest some thing

$ ls -ltr test2.webM
-rw-r--r-- 1 spamarth users 15010 Nov 5 16:34 test2.webM
$ sed '${/^$/!s/$//;}' test2.webM > ./test2
$ ls -ltr test2.webM test2
-rw-r--r-- 1 spamarth users 15010 Nov 5 16:34 test2.webM
-rw-r--r-- 1 spamarth users 0 Nov 5 16:35 test2

bup-restore

bup-restore(1)						      General Commands Manual						    bup-restore(1)

NAME

       bup-restore - extract files from a backup set

SYNOPSIS

       bup restore [--outdir=outdir] [-v] [-q]

DESCRIPTION

       bup restore extracts files from a backup set (created with bup-save(1)) to the local filesystem.

       The specified paths are of the form /branch/revision/path/to/file.  The components of the path are as follows:

       branch the name of the backup set to restore from; this corresponds to the --name (-n) option to bup save.

       revision
	      the  revision of the backup set to restore.  The revision latest is always the most recent backup on the given branch.  You can dis-
	      cover other revisions using bup ls /branch.

       /path/to/file
	      the original absolute filesystem path to the file you want to restore.  For example, /etc/passwd.

       Note: if the /path/to/file is a directory, bup restore will restore that directory as well as recursively restoring all its contents.

       If /path/to/file is a directory ending in a slash (ie.  /path/to/dir/), bup restore will restore the children of that directory directly to
       the  current directory (or the --outdir).  If the directory does not end in a slash, the children will be restored to a subdirectory of the
       current directory.  See the EXAMPLES section to see how this works.

OPTIONS

       -C, --outdir=outdir
	      create and change to directory outdir before extracting the files.

       -v, --verbose
	      increase log output.  Given once, prints every directory as it is restored; given twice, prints every file and directory.

       -q, --quiet
	      don't show the progress meter.  Normally, is stderr is a tty, a progress display is printed that shows the  total  number  of  files
	      restored.

EXAMPLE

       Create a simple test backup set:

	      $ bup index -u /etc
	      $ bup save -n mybackup /etc/passwd /etc/profile

       Restore just one file:

	      $ bup restore /mybackup/latest/etc/passwd
	      Restoring: 1, done.

	      $ ls -l passwd
	      -rw-r--r-- 1 apenwarr apenwarr 1478 2010-09-08 03:06 passwd

       Restore the whole directory (no trailing slash):

	      $ bup restore -C test1 /mybackup/latest/etc
	      Restoring: 3, done.

	      $ find test1
	      test1
	      test1/etc
	      test1/etc/passwd
	      test1/etc/profile

       Restore the whole directory (trailing slash):

	      $ bup restore -C test2 /mybackup/latest/etc/
	      Restoring: 2, done.

	      $ find test2
	      test2
	      test2/passwd
	      test2/profile
