removing newlines from a file?

phrakture · 2005-04-07 20:33:50

ok, I want to remove all newlines from a file... I don't think sed will work, as it reads line by line.... does anyone know a way to do this?

FYI, I have an xml file, some 8000 lines long, which has some bad newlines just due to the sheer size... as in:

<someNode a="a" b="b" something="som<NEWLINE>
ething"/>

and I want it to go away 8(

why does nobody like tr?
echo -e "n" | tr -d 'n'

wow, rock on!
there's little utilities like that that I totally forget about all the time...

kinda like "modinfo"

Took me way too long to discover "tee"...

in python there is replace() method, like...

file = open("path/to/file", "r")
string = file.read()
file.close()
string_new = string.replace("n", "")
file = open("/path/to/file_new", "w")
file.write(string_new)
file.close()

that should fix it,

I tried that in .NET, actually, and for some reason it wasn't working.... the basic process was:
call a stored procedure
convert massive results to XML
stream XML to file

real simple... however String.Replace wasn't doing crap for the newlines... I dunno why...but it always had embedded newlines at the worst places...

seeing as this is one of those apps where ya go "aha something changed, time to regenerate the XML file" every month or so, it wasn't important *how* it's done... so I was just going to pipe it to tr (found a windows version).

On a side note, I did get the procedure down from taking ~7mins to run to under a minute... hooray for optimization!

It's possible but tr is much easier. See 5.10 from

vim -c '%s/n//' <file>

If I got the question right. :-)
