getting rid of ^B

[tvlad]

If i edit a file in windows, and then copy it to linux, if it's a script or smth like that it won't run.When i do vim -b on the file, i find that on every line it has ^B.

 

Now, there must be a way to get rid of those ^B.Is there a windows utility, or

should i do it in linux (it can be done, but how ? ) :D

[tyme]

what are you using to edit the file in windows?

[Cannonfodder]

You probably just need to convert the carriage returns from windows to linux..

[tvlad]

Yup, but how do i do that ???

[aru]

~$ sed 's/^B//g' yourfile > yournewfile

 

enter "^B" by typing "ctrl-v ctrl-b"

[tvlad]

First, it isn't ^B, it's ^M.

 

#^M

# Log:^M

#^M

# 0.77s - Changed the default block behavior to REJECT not DROP^M

# 0.76s - Added a comment about the OPTIONAL WWW ruleset and a comment^M

# where to put optional PORTFW commands^M

# 0.75s - Added clarification that PPPoE users need to use^M

 

And i tryed using that sed command on this file, but no change (ofcourse i pu ^M instead of ^B in the command, ain't THAT dum ).

[tyme]

you could always use a text editor in linux that has a replace feature (such as gedit) and change ever ^M to an empty space...assuming the ^M shows up in the editor.

[tvlad]

There must be a way to do it from text mode.

First, it isn't ^B, it's ^M.

 

#^M

# Log:^M

#^M

#   0.77s - Changed the default block behavior to REJECT not DROP^M

#   0.76s - Added a comment about the OPTIONAL WWW ruleset and a comment^M

#           where to put optional PORTFW commands^M

#   0.75s - Added clarification that PPPoE users need to use^M

 

And i tryed using that sed command on this file, but no change (ofcourse i pu ^M instead of ^B in the command, ain't THAT dum ).

 

Well you said ^B, didn't you?

 

the way to type ^M is "ctrl-v ctrl-ENTER", it isn't obvious, is it? so no you aren't dumb :D

 

Do it again with sed

 

or if you prefer vim, use the command ":%s/^M//g"

[tvlad]

Nope, doesn't work, all i want to do is to remove those ^M from the file.

Having heard of a program, and using this_google_search I found a reference to it at this link;

http://www.leuf.net/cgi/wikidn?WikiWaySources

search the page for fromdos. It's about halfway down. There's also dos2unix if you read on.

[bvc]

BTW, I think dos2unix is on the CD's. I've seen it several times somewhere? A

urpmf dos

will tell you. :wink:

[tvlad]

Thx Bvc, though i'm wandering, couldn't it be done with awk, sed or some other very common tools ????

[bvc]

I think the page gave an example, and a perl script. I'm sure there is with common tools but that's not my area....it's aru's. :P He'll figure it out. Like the rest of us, aru hates to be defeated :wink:

Ofcourse! The way I showed you works, I've done it dozens of times! :shock:

 

with sed:

~$ sed 's/^M//g' file.dos > file.unix

 

with awk:

~$ awk 'gsub("^M","")' file.dos > file.unix

 

with vi (edits directly the file):

~$ vim -c ':%s/^M//g 

:wq

' file.dos

 

Isn't that enough!

 

Remember '^M' is -------> 'ctrl-v ctrl-ENTER'
