Re: Backup script runs on AIX but not on Linux

The "vi" command "set list" will do the same;  just enter it at the "colon" prompt once you're in "vi".  Then, "set nolist" will turn it off.

To get rid of the "invisible" carriage-return (i.e. "^M") characters, you can use the "vi" command ":s/^V^M//", which translates (in keystrokes) to:
  • char ":" (a.k.a. "colon") to enter "vi" command mode
  • letter "s" (for the "substitute" command in "ex" and "vi")
  • char "/" (a.k.a. "forward slash" for "begin search pattern")
  • CTRL-v
  • CTRL-m
  • char "/" (a.k.a. "forward slash" for "end search pattern, begin replace pattern")
  • char "/" (a.k.a. "forward slash" for "end (empty) replace pattern")
  • then hit <return> (to let 'er rip)

Yes, that’s normal with vi on Linux – this drove me crazy for an hour or two when I first started working on Linux too.  For some reason the Linux version of vi doesn’t show the DOS characters, but if you look at the bottom line of your vi window it should say [dos] if they are present, like this:

 

-------------------------------------------------------

myhost>vi testfile.txt

This

is

my

test

file

~

~

"testfile.txt" [dos] 5L, 27C          1,1           All

-------------------------------------------------------

 

The only way I know of to make it display the characters is with the very cryptic command “:edit ++ff=unix”, e.g.:

 

-------------------------------------------------------

myhost>vi testfile.txt

This ^M

is^M

my^M

test^M

file^M

~

~

:edit ++ff=unix

-------------------------------------------------------

 

Also, beware that this problem will occur whether you transfer the file via FTP (in either binary or ascii mode), or SCP.

I ran dos2unix on the script and it fixed it.  Even though I couldn't see any DOS characters, they must have been there somewhere because this fixed the problem.
