backslash input in script

esasse · 02-17-2005, 05:55 AM

Hello,

I'm trying to write a script to install a software and the user have to input a Windows UNC path, like \\server\share and I'm using:

echo -n "Path:"
read caminho

Then the user types "\\server\share", but when I try to echo it to a file I got "\servershare".

How can I tell the script to ignore and don't interpret the backslashs as scape characters?

Thanks!

Use another backslash to escape "\", like this:
\\\\server\\share

Thanks, I know this way.

But I hope there is another way so that I don't need to instruct my users to input doubled slashs.
Is there a way?

Then do a "read -r caminho" to let "\" be interpreted literally.

Thanks bathory! It working now!

Just one more doubt how can I check if the user type a backslash at the end, like:

\\server\share

or

\\server\share\

Because I need to concatenate a filename after the path.

(Side-note: with single quotes '\\server', \ are not interpreted by the shell.)

Let's say your server name is $MyServer, and is equal to either '\\server\share' or '\\server\share\', and you want to append the value of RelativePath, that looks like 'relative\path' or '\relative\path'. Do it this way in bash:

Code:

AbsolutePath="${MyServer%/}/${RelativePath#/}"

As a quick solution add:

Code:

caminho="${caminho/%\\/}"

to remove the trailing "\" if exists and concatenate "\filename"
