assigning a string with '/' from $1 to a variable

hi all

i tried this in numerous ways,
but i just can't seem to make this work.

i want to make an alias that takes a windows network path (\\blabla\bla\bla)
and reverts the slashes (\\blabla\bla\bla > //blabla/bla/bla)
then cd's into the output.

if i do an #echo \\blabla\bla\bla | tr '\' '/'
it works fine, but if i try to assign this to a variable, then
it writes it with one slash and without the others in the argument , like so :
/blablablabla

even if the variable input comes form the #echo command.

please help. this is annoying!

Hi and welcome to LQ.
\ is an escape character and as such should be escaped. Try this:

Code:

a=$(echo \\\\blabla\\bla\\bla | tr '\' '/')

echo $a

Or put the problem string in single quotes:

Code:

c@CW8:/tmp$ echo '\\blabla\bla\bla' | tr '\' '/'

tr: warning: an unescaped backslash at end of string is not portable

//blabla/bla/bla

c@CW8:/tmp$ echo '\\blabla\bla\bla' | tr '\' '/' 2>/dev/null

//blabla/bla/bla

I am not sure I see the problem?

Code:

v='\\blabla\bla\bla'



echo cd "${v//\\//}"

Not sure how the extra '/' at the start will play out for you.
