I use grep all the time. Don't have a problem understanding it. But I am looking at a script that uses 'eprep'. Basically we have something that uses ssh to log into a remote host and execute a "df -h" and emails us. We use that to check space on remote machines. Lately I have noticed the 'egrep' command isn't returning anything. Someone else who is no longer around wrote this. I don't understand what the statement is doing. On one machine it returns what I would expect, on others, it returns nothing. On a working machine:
Machine that doesn't work:
If I leave off the egrep, I do see the output of the df command, so I am sucessfully logging into the remote machine.

Hi,
I am wondering if it's possible to link multiple patterns with egrep.
Here here is what I am doing :
grep -v ";;" | grep -v ARC_TIME | grep -v \* | grep -v STAS0 Can I do all of this by invoking egrep just once ?
Thanks (4 Replies)

ssh-copy-id
SSH-COPY-ID(1) General Commands Manual SSH-COPY-ID(1)NAME
ssh-copy-id - install your public key in a remote machine's authorized_keys
SYNOPSIS
ssh-copy-id [-i [identity_file]] [user@]machine
DESCRIPTION
ssh-copy-id is a script that uses ssh to log into a remote machine and append the indicated identity file to that machine's ~/.ssh/autho-
rized_keys file.
If the -i option is given then the identity file (defaults to ~/.ssh/id_rsa.pub) is used, regardless of whether there are any keys in your
ssh-agent. Otherwise, if this:
ssh-add -L
provides any output, it uses that in preference to the identity file.
If the -i option is used, or the ssh-add produced no output, then it uses the contents of the identity file. Once it has one or more fin-
gerprints (by whatever means) it uses ssh to append them to ~/.ssh/authorized_keys on the remote machine (creating the file, and directory,
if necessary.)
NOTES
This program does not modify the permissions of any pre-existing files or directories. Therefore, if the remote sshd has StrictModes set in
its configuration, then the user's home, ~/.ssh folder, and ~/.ssh/authorized_keys file may need to have group writability disabled manu-
ally, e.g. via
chmod go-w ~ ~/.ssh ~/.ssh/authorized_keys
on the remote machine.
