Hello batchenr,

Please always mention sample Input_file into your posts into code tags so that we could understand the requirement clearly. So I am assuming this could be your possible Input_file by taking some test sample.
Code:
cat Input_file
#test1 test2 test3 bla bla
test2 test3 chumma chuma1
##test2 test4 test5 test6
chumma1 test2 chumma3

Now I am running following code.
Code:
awk '/^#/{sub(/^#*/,"");print}'   Input_file

Output will be as follows.
Code:
test1 test2 test3 bla bla
test2 test4 test5 test6

Now if above code is NOT meeting your requirements then kindly post sample Input_file in code tags and show us sample output too in code tags so that we could understand the question properly. I hope this helps you.


Thanks,
R. Singh

rdup-up

RDUP-UP(1)							       rdup								RDUP-UP(1)

NAME

       rdup-up - update a directory tree with a rdup archive

SYNOPSIS

       rdup-up [OPTION]...  DIRECTORY

DESCRIPTION

       With rdup-up you can update an (possibly) existing directory structure with a rdup archive.

       The rdup archive has to be given to rdup-up's standard input.

   Username and uids
       rdup  outputs  both  the  username  and	uid, the receiving system (which may be a totally different system) checks if the username and uid
       match. If the username and uid don't match the (numeric) uid is used on the file. The same holds true for the groupname and gid.

OPTIONS

       -n     Do a dry-run and do not create anything on disk.

       -t     Create DIRECTORY (ala mkdir -p) if it does not exist.

       -s N   Strip N path components from a pathname. If the resulting pathname is empty after this operation it is skipped. Be  careful  however
	      with the following structure:

		  /foo
		  /foo/bar
		  /foo/bar/bla.txt
		  /foo/blork/bla.txt

	      With rdup-up -s2 this will leave:

		  <empty>
		  <empty>
		  /bla.txt
		  /bla.txt

	      And the last 'bla.txt' will overwrite the previous one, this will happen without warnings.

       -r PATH
	      This option is related to the -s option, but works different. The string PATH is removed from (the beginning of) each pathname. With
	      -r /home/backup the pathname /home/backup/bin/mycmd becomes /bin/mycmd. The same could be done with -s 2, but then you need to count
	      the slashes. Note -s is always performed before -r.

       -v     Be more verbose and echo the processed files to standard output.

       -vv    Be even more verbose and echo processed file and the uid and gid information to standard output.

       -T     Show  a  table  of  contents of the rdup stream received (ala tar -tf -).  With -T the directory argument is optional. -T unsets any
	      verbose (-v) options.

       -h     A short help message.

       -V     Show the version.

EXIT CODE

       rdup-up return a zero exit code on success, otherwise 1 is returned.
