Shell Programming and Scripting

i have to print in a html file directories like this

Code:

/home/user
/home/user/dir

but the problem is that when i us this comand

Code:

listado=`find $direcreal -type f -print`

i get this

Code:

/home/user /home/user/dir1

i try with sed to replace the space with an enter

Code:

mostrarlistado=`echo "$listado" | sed "s/\ /\n/g"`

but i keep printing the same result

You'll have to quote it correctly. Compare the output of

Code:

echo $mostrarlistado

to

Code:

echo "$mostrarlistado"

Try it with tr instead of sed:

Code:

tr " " "\n"

with tr " " "\n" i get the same result
/home/user /home/user/dir1

Maybe your problem is in the actual HTML? If you're using the results straight from sed, you're probably getting something like this:

Code:

<div id="blablabla">
/home/user
/home/user/dir
</div>

And if that's the case, you're missing the <br /> tag that signals a line break in HTML. If I remember correctly, implicit line breaks like the ones above turn into spaces when HTML is rendered on to a webpage.

So, if this is your problem, try replacing the spaces with "<br />" instead of newlines.

It is like Pludi says, just do a:

Code:

echo "$listado"

All right, now I got it!

Code:

find $direcreal -type f -print

This already prints file names separated/delimited by "\n", but then you assign this output to a variable, where AFAIK all "\n" get converted to a whitespace. Later you actually do the same with another variable.
Why not simply redirect the output of the find command to a file?
