Hello I'm trying to write a shell script which can remove a carriage return and/or line feed from a file, so the resulting file all ends up on one line.
So, I begin with a file like this
text in file!<CR>
line two!<CR>
line three!<CR>
END!<CR>
And I want to end up with a file... (1 Reply)
I am using AIX and ksh.
I need to display the contents of a file that has a pid (process id). Because the file is open, it doesn't have the line feed or new line, so for some reason if I do this:
`cat $pid` , where $pid is the name of the fully qualified file, it displays

col
COL(1) BSD General Commands Manual COL(1)NAME
col -- filter reverse line feeds from input
SYNOPSIS
col [-bfhpx] [-l num]
DESCRIPTION
The col utility filters out reverse (and half reverse) line feeds so that the output is in the correct order with only forward and half for-
ward line feeds, and replaces white-space characters with tabs where possible. This can be useful in processing the output of nroff(1) and
tbl(1).
The col utility reads from the standard input and writes to the standard output.
The options are as follows:
-b Do not output any backspaces, printing only the last character written to each column position.
-f Forward half line feeds are permitted (``fine'' mode). Normally characters printed on a half line boundary are printed on the fol-
lowing line.
-h Do not output multiple spaces instead of tabs (default).
-l num Buffer at least num lines in memory. By default, 128 lines are buffered.
-p Force unknown control sequences to be passed through unchanged. Normally, col will filter out any control sequences from the input
other than those recognized and interpreted by itself, which are listed below.
-x Output multiple spaces instead of tabs.
In the input stream, col understands both the escape sequences of the form escape-digit mandated by Version 2 of the Single UNIX
Specification (``SUSv2'') and the traditional BSD format escape-control-character. The control sequences for carriage motion and their ASCII
values are as follows:
ESC-BELL reverse line feed (escape then bell).
ESC-7 reverse line feed (escape then 7).
ESC-BACKSPACE half reverse line feed (escape then backspace).
ESC-8 half reverse line feed (escape then 8).
ESC-TAB half forward line feed (escape than tab).
ESC-9 half forward line feed (escape then 9). In -f mode, this sequence may also occur in the output stream.
backspace moves back one column (8); ignored in the first column
carriage return (13)
newline forward line feed (10); also does carriage return
shift in shift to normal character set (15)
shift out shift to alternate character set (14)
space moves forward one column (32)
tab moves forward to next tab stop (9)
vertical tab reverse line feed (11)
All unrecognized control characters and escape sequences are discarded.
The col utility keeps track of the character set as characters are read and makes sure the character set is correct when they are output.
If the input attempts to back up to the last flushed line, col will display a warning message.
ENVIRONMENT
The LANG, LC_ALL and LC_CTYPE environment variables affect the execution of col as described in environ(7).
EXIT STATUS
The col utility exits 0 on success, and >0 if an error occurs.
SEE ALSO colcrt(1), expand(1), nroff(1), tbl(1)STANDARDS
The col utility conforms to Version 2 of the Single UNIX Specification (``SUSv2'').
HISTORY
A col command appeared in Version 6 AT&T UNIX.
