Replace ^Z Character

Hello,

I am trying to replace all ^Z chars in my file to a space using the following command:


Code:
cat <file> | tr '\32' ' '

But the above command is deleting all NULL in the file. Hence the field positions are being changed. Please let me know the reason, if anyone knows.

Thanks in advance !!!

This works for me:
Code:
$ tr '\32' ' ' < file1 > file2

Code:
$ cat -v file1
A C 6 T^Z
C^ZB 4 R
A B 3 T^Z
D E 5 4

$ cat -v file2
A C 6 T 
C B 4 R
A B 3 T 
D E 5 4

Still, the NULL is also getting deleted (\0). How can i delete only 032 (^Z) ?

Hmm. That's not happening for me.

Code:
$ cat -v <(tr '\32' ' ' < file1)
A C^@ 6 T 
C B 4 R
A B 3 T 
D E 5 4

$ od -b file1
0000000   101 040 103 000 040 066 040 124 032 012 103 032 102 040 064 040
0000020   122 012 101 040 102 040 063 040 124 032 012 104 040 105 040 065
0000040   040 064 012

$ od -b file2
0000000   101 040 103 000 040 066 040 124 040 012 103 040 102 040 064 040
0000020   122 012 101 040 102 040 063 040 124 040 012 104 040 105 040 065
0000040   040 064 012

If you're outputting it to the terminal, that would eat it up, so you wouldn't see it.

did you try it in Solaris or Red hat ?

I 'tried it out' in OS X, and don't see why Red Hat or Solaris would be any different.

Hmm .. I was not sure so wanted to check with you. Can you please tell me how to insert a NULL in vi editor ?

I don't want to touch the production file.
