Thanks for your response! but i couldnt get it to work, i tried:

Code:
# sed /[0-9]\{4,\}\|[0-9]\{1\}.*[0-9]\{1\}.*[0-9]\{1\}.*[0-9]\{1\}/d infile

But that didnt change anything, notice that i dont use single quotes cause i dont know how to write them in gnuwin, i press alt+39 and instead of getting " ' " i get something like this " ` " and i get "unknown command", could that be the reason?

And to make it "delete lines with more than 4 numbers" it would be something like these right?

Code:
# sed /[0-9]\{5,\}\|[0-9]\{1\}.*[0-9]\{1\}.*[0-9]\{1\}.*[0-9]\{1\}.*[0-9]\{1\}/d infile

But since i am doing something wrong or the code is missing something it doesn't work.

Then regarding this:
Code:
### justdoit ###
# "find the line more than 3 numbers" or/and "less than 4 characters"
 
#!/bin/bash
 while read -r l
 do
   if [ $(echo "$l" | tr -d '[:alpha:]' | sed 's/ *//g' | wc -c) -gt 4 ] ; then
        `sed -i "/$l/d" infile`

   elif [ $(echo "$l" | tr -d '[:digit:]' | sed 's/ *//g' | wc -c) -lt 5 ] ; then
        `sed -i "/$l/d" infile`

   else
        echo "line has different condition->" `sed -n "/$l/p" infile`
   fi
 done < infile
 more a

I like this code, since this section of the code:

Code:
   if [ $(echo "$l" | tr -d '[:alpha:]' | sed 's/ *//g' | wc -c) -gt 4 ] ; then
        `sed -i "/$l/d" infile`

is a lot simpler than getting the same results on "sed" alone, but i dont have "bash" in my gnuwin32 files, i downloaded it, but can it be used from the gnuwin32 console at all? i couldn't even run the install from the bash folder.


Sorry but as i said, i dont know anything about this, so i can do little on my own.

nwbpset

NWBPSET(1)							      nwbpset								NWBPSET(1)

NAME

       nwbpset - Create a bindery property or set its value

SYNOPSIS

       nwbpset [ -h ] [ -S server ] [ -U user name ] [ -P password | -n ] [ -C ]

DESCRIPTION

       nwbpset Reads a property specification from the standard input and creates and sets the corresponding property. The format is determined by
       the output of 'nwbpvalues -c'. nwbpset will hopefully become an important part of the bindery management  suite	of  ncpfs,  together  with
       'nwbpvalues -c'. See util/nwbpsecurity for an example.

       As another example, look at the following command line:

	 nwbpvalues -t 1 -o supervisor -p user_defaults -c |
	 sed '2s/.*/ME/'|
	 sed '3s/.*/LOGIN_CONTROL/'|
	 nwbpset

       With  this command, the property user_defaults of the user object 'supervisor' is copied into the property login_control of the user object
       'me'.

	 nwbpvalues -t 1 -o me -p login_control -c |
	 sed '9s/.*/ff/'|
	 nwbpset

       This command disables the user object me.

       Feel free to contribute other examples!

       nwbpset looks up the file $HOME/.nwclient to find a file server, a user name and possibly a password. See nwclient(5) for more information.
       Please note that the access permissions of $HOME/.nwclient MUST be 600 for security reasons.

OPTIONS

       -h
	  -h is used to print out a short help text.

       -S server
	  server is the name of the server you want to use.

       -U user
	  user is the user name to use for login.

       -P password
	  password  is	the  password to use for login. If neither -n nor -P are given, and the user has no open connection to the server, nwbpset
	  prompts for a password.

       -n
	  -n should be given if no password is required for the login.

       -C
	  By default, passwords are converted to uppercase before they are sent to the server, because most servers require this. You can turn off
	  this conversion by -C.
