hi,

i tried to redirect the output of (#man bash > bash) file.

after that when i tried open with vi , i got the ^H characters.

please find the attachments 1.txt 2.GUI

when i tried to remove the same with following commands nothing succeeded.

# uname -a
Linux node1.localdomain 2.6.32-71.el6.x86_64 #1 SMP Wed Sep 1 01:33:01 EDT 2010 x86_64 x86_64 x86_64 GNU/Linux
#file bash
bas: ASCII English text, with overstriking
# sed -i 's/^H//g' bash
# sed -i 's/\^H//g' bash
# sed -i 's/\^[*H]//g' bash
# tr -d '^H' < bash

In vi, type Ctrl-V then Ctrl-H to enter the match you want.

(mainly to give this a non-zero reply count...)
The '^H' is actually a SINGLE [control] character: backspace. (see man ascii)
(I hope you aren't typing TWO chars in those cmds you tried: shift-six ^ plus an H is UNrelated!)
Look into using these two keystrokes: ctrl-v ctrl-h in vi. Like:
:%s/ctrl-v ctrl-h//g
Again, those are *only two* keystrokes, holding the control key down. And NO space!

Best wishes!

As the others have answered your issue, I thought I would just add that it is a bad idea to use the name of a command for the name of your file, ie. bash itself is an executable command.

Manpages are stored in nroff format. You can also use the following command to covert a man page to plain text.

man bash | col -b > bash.txt

michaelk , it worked from your command.

Thanks all for your time.
