Hi,
I am simply trying to remove the header row from a file using sed, but I'm running into strange difficulties.
It seems that in addition to removing the first line, this command is also removing the last line (or more specifically, clearing the last line, since the line is still counted even though it's empty).
For what it's worth, I've included several versions of the sed command all exhibiting the same behavior.
Hi all,
I've searched the web and this forum for this but not had any luck. I'm trying to use sed so when it finds a space it will insert a new line.
What i have is a file containing .e.g
1 2 4 7 9
and want it to look like
1
2
4
7
9
I've tried:
more test2 | sed 's/ /\\n/g'... (1 Reply)
For lists in sed, to say what to replace, is this correct:
I am hoping that this would recognise that either a "." is present, or that the substitution happens at the end of the line.
For files with extensions , my script works perfectly.
My problem is, files without extentions, i.e. . ... (1 Reply)
Hi,
I want to use the sed command to delete some lines in a file and I was wondering whether there is a possibility of knowing which lines are deleted, or at least which line numbers.

Using cat file.txt | sed -e :a -e '/$/N;s/\n/ /;ta' the output in file.txt should go from

3to 1 2 3 instead I only get the last line or 3.
I find that if I open the file in gedit and hit delete in front of every... (7 Replies)

If I have this:
perl -pne 's/img_onload.{8}//g'
How would I do to instead of replacing img_onload.{8} with "nothing", get "nothing" to be a deleted line? Kind of the opposite to \n. (2 Replies)
I was using the following option to clean up the ^M characters in a file that was FTPed from Windows:
- dos2unix
- sed 's/^M//g'
The ^M characters are removed but the last line is also getting removed. Any idea why this is happening.

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
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.
