echo $PATH | sed 's/:/\n/g'
echo $PATH | sed 's/:/"\n"/g'
echo $PATH | sed 's/:/\\n/g'
echo $PATH | sed 's/:/"\\n"/g'
echo $PATH | sed "s/:/\n/g"
echo $PATH | sed "s/:/\\n/g"
hmm something wrong with my shell ...
No, There isn't. The problem is that you don't realize that most sed implementations do not support a \n escape sequence in the replacement text of a substitution command.

That means my shell has problems to interpret well the '\'
No. As with \n, most sed implementations do not support a \t escape sequence in the replacement text of a substitution command.
tcsh has many design flaws, such as this one. I suggest using any shell but tcsh, where strings containing newlines will be valid instead of syntax errors.
I'd like to question your presuppositions: why do you need to put newlines into your PATH variable? If it is because you want to work on its parts in a loop of some sort this might also work for you, without the need for "sed" or any other tool:
Code:
IFS=":" for var in $PATH ; do
echo var is: \"$var\"
done
Example:
I have server name A with an IP : 125.252.235.455
I have an username /password to login into this server under SSH connection
In this server i have a path /apps/user/filename(Big.txt)
Everyday we used to get the filename as Big.txt.

I have developed a script that transfers files from a UNIX machine to a Windows machine. Transferring the files is working perfectly, but my echo statements are displaying the destination (Windows) path names incorrectly.

Hi I'm trying to select text between two lines, I'm using sed to to this, but I need to pass variables to it. For example

I need to run my shell script just by typing its name rather than doing sh <scrpit name>. I think its something to do with my profile and path.
echo $path is giving me output as follows:

This is on a Solaris 9 box, but I feel like a noob, so I am posting here. When I echo $PATH I get a lot of duplicate paths and extra stuff I don't need. What I want is just what I set up in my home dir under .profile
My login shell=/bin/bash
I checked the following and there are no path... (1 Reply)
