Okay we've got past one very common scripting problem ("for" vs "while").
Back to the Microsoft text file format problem in your data files (imho).
I believe that your display format is all over the place because the input data contains carriage-return characters (or some other weird control codes which do not belong in a unix text file) and you have in places deleted line-feed characters (the standard unix text file line terminator). Therefore I believe that what you are seeing on the screen is only part of the output from your script because the screen driver is actioning these rogue control codes.
Back to an earlier request. We need to see a sample .svn/entries file displayed in a manner where we can see control codes:
For example:
Also, please post the current version of the script. I can't see anything in the most recent version posted which writes to a file (unless you are referring to a saved file from "script").
We'll come back to the code at the bottom of post #24 if necessary, but I for one can't follow it!

Hi,
I'm new to shell programming.
I have two variables a and b
a=val1
b=val2
could anyone kindly post the shell script to concatenate the values of variable a and b with an underscore(_) in between?
The final output should be val1_val2. (8 Replies)

col
col(1) User Commands col(1)NAME
col - reverse line-feeds filter
SYNOPSIS
col [-bfpx]
DESCRIPTION
The col utility reads from the standard input and writes to the standard output. It performs the line overlays implied by reverse line-
feeds, and by forward and reverse half-line-feeds. Unless -x is used, all blank characters in the input will be converted to tab characters
wherever possible. col is particularly useful for filtering multi-column output made with the .rt command of nroff(1) and output resulting
from use of the tbl(1) preprocessor.
The ASCII control characters SO and SI are assumed by col to start and end text in an alternative character set. The character set to which
each input character belongs is remembered, and on output SI and SO characters are generated as appropriate to ensure that each character
is written in the correct character set.
On input, the only control characters accepted are space, backspace, tab, carriage-return and newline characters, SI, SO, VT, reverse line-
feed, forward half-line-feed and reverse half-line-feed. The VT character is an alternative form of full reverse line-feed, included for
compatibility with some earlier programs of this type. The only other characters to be copied to the output are those that are printable.
The ASCII codes for the control functions and line-motion sequences mentioned above are as given in the table below. ESC stands for the
ASCII escape character, with the octal code 033; ESC- means a sequence of two characters, ESC followed by the character x.
reverse line-feed ESC-7
reverse half-line-feed ESC-8
forward half-line-feed ESC-9
vertical-tab (VT) 013
start-of-text (SO) 016
end-of-text (SI) 017
OPTIONS -b Assume that the output device in use is not capable of backspacing. In this case, if two or more characters are to appear in the
same place, only the last one read will be output.
-f Although col accepts half-line motions in its input, it normally does not emit them on output. Instead, text that would appear
between lines is moved to the next lower full-line boundary. This treatment can be suppressed by the -f (fine) option; in this case,
the output from col may contain forward half-line-feeds (ESC-9), but will still never contain either kind of reverse line motion.
-p Normally, col will ignore any escape sequences unknown to it that are found in its input; the -p option may be used to cause col to
output these sequences as regular characters, subject to overprinting from reverse line motions. The use of this option is highly
discouraged unless the user is fully aware of the textual position of the escape sequences.
-x Prevent col from converting blank characters to tab characters on output wherever possible. Tab stops are considered to be at each
column position n such that n modulo 8 equals 1.
ENVIRONMENT VARIABLES
See environ(5) for descriptions of the following environment variables that affect the execution of col: LC_CTYPE, LC_MESSAGES, and
NLSPATH.
EXIT STATUS
The following error values are returned:
0 Successful completion.
>0 An error occurred.
ATTRIBUTES
See attributes(5) for descriptions of the following attributes:
+-----------------------------+-----------------------------+
| ATTRIBUTE TYPE | ATTRIBUTE VALUE |
+-----------------------------+-----------------------------+
|Availability |SUNWesu |
|CSI |enabled |
+-----------------------------+-----------------------------+
SEE ALSO nroff(1), tbl(1), ascii(5), attributes(5), environ(5)NOTES
The input format accepted by col matches the output produced by nroff with either the -T37 or -Tlp options. Use -T37 (and the -f option of
col) if the ultimate disposition of the output of col will be a device that can interpret half-line motions, and -Tlp otherwise.
col cannot back up more than 128 lines or handle more than 800 characters per line.
Local vertical motions that would result in backing up over the first line of the document are ignored. As a result, the first line must
not have any superscripts.
