variables in sed

Using variables in sed scripts is tricky, and it looks like you're caught on the first step.

Ever program in C? When this command runs:

sed -e 's/$source/$target/g' $remotedir/$source.mg

think about the values of argv.

What I imagine you WANT is for argv[2] to be something like:

s/\/old\/directory\/oldfile/\/new\/directory\/newfile/

What you HAVE is:

s/$source/$target/g

Because you're using single quotes, not double quotes, and sh isn't expanding those variables.

So the first step is to switch those single quotes to double quotes,

"s/$foo/$bar/g"

The next step is to make sure $foo and $bar don't contain any stray '/' characters that are going to confuse sed.

Best of luck!

The problem here is: 's/$source/$target/g'


---

for after in `cat after.conf`
do
echo $target
$adminssh sed -e 's/$source/$target/g' $remotedir/$source.mg > $target.mg

done

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.
