Hey guys, thanks for the replies. Much appreciated!
The sed command gave some strange results, and with the character locations not being preserved, I won't be able to find what I'm looking for in the file.
Thanks for the info on cat, but that just shows me what non-printing characters are in there and by removing the control chars it won't preserve how the text looks when printed using just 'cat filename.txt'....
I guess maybe this isn't possible..? I thought maybe it would be since the escape sequences are just re-arranging the text (*and inserting whitespace) and I can physically see how the formatted data SHOULD look when printed in the terminal. So I guess I kind of hoped I could just capture what is actually seen in the terminal and NOT what is unseen, like escape sequences/control-characters...
Thanks Again,
Matt

To explain a little better of what I'm trying to do see below, *maybe there is a simpler way....
So what the goal is, I'm trying get the output of the AIX command "topas" into a text file so I can grab one specific value... This command is very similar to the top command where it is an interactive command which just continuously updates the terminal window with new values every 2 seconds... Since it does that, that is why the control characters show up in the text file. They use the control characters to place the values correctly on the screen.
If you redirect topas to a text file and kill it right away, and then do a vi / view of the file the values are all over the place. It seems like it shows some of the Value's labels in the correct spot but their actual values could show up 20 lines below where it would be if you just did a 'cat' on the file.
I was praying topas had a command line switch similar to top's "-b" option for batch mode, but it does not...
There is a way to record the topas command's values with the topasrec command, but the output from that is harder to understand then just using topas. And I believe you need to use something like Excel to read that file....
I guess if there isn't another way I can just do what I'm already doing and see if that Label's value shows up on the exact same line everytime... If it does, I can just hard-code it in to capture that specific line and pull out the value... But, I guess we'll see.
Thanks Again,
Matt

cat(1) User Commands cat(1)
NAME
cat - concatenate and display files
SYNOPSIS
cat [-nbsuvet] [file...]
DESCRIPTION
The cat utility reads each file in sequence and writes it on the standard output. Thus:
example% cat file
prints file on your terminal, and:
example% cat file1 file2 >file3
concatenates file1 and file2, and writes the results in file3. If no input file is given, cat reads from the standard input file.
OPTIONS
The following options are supported:
-n Precede each line output with its line number.
-b Number the lines, as -n, but omit the line numbers from blank lines.
-u The output is not buffered. (The default is buffered output.)
-s cat is silent about non-existent files.
-v Non-printing characters (with the exception of tabs, new-lines and form-feeds) are printed visibly. ASCII control characters
(octal 000 - 037) are printed as ^n, where n is the corresponding ASCII character in the range octal 100 - 137 (@, A, B, C, . . .,
X, Y, Z, [, , ], ^, and _); the DEL character (octal 0177) is printed ^?. Other non-printable characters are printed as M-x,
where x is the ASCII character specified by the low-order seven bits.
When used with the -v option, the following options may be used:
-e A $ character will be printed at the end of each line (prior to the new-line).
-t Tabs will be printed as ^I's and formfeeds to be printed as ^L's.
The -e and -t options are ignored if the -v option is not specified.
OPERANDS
The following operand is supported:
file A path name of an input file. If no file is specified, the standard input is used. If file is `-', cat will read from the
standard input at that point in the sequence. cat will not close and reopen standard input when it is referenced in this
way, but will accept multiple occurrences of `-' as file.
USAGE
See largefile(5) for the description of the behavior of cat when encountering files greater than or equal to 2 Gbyte ( 2**31 bytes).
EXAMPLES
Example 1: Concatenating a file
The following command:
example% cat myfile
writes the contents of the file myfile to standard output.
Example 2: Concatenating two files into one
The following command:
example% cat doc1 doc2 > doc.all
concatenates the files doc1 and doc2 and writes the result to doc.all.
Example 3: Concatenating two arbitrary pieces of input with a single invocation
The command:
example% cat start - middle - end > file
when standard input is a terminal, gets two arbitrary pieces of input from the terminal with a single invocation of cat. Note, however,
that if standard input is a regular file, this would be equivalent to the command:
cat start - middle /dev/null end > file
because the entire contents of the file would be consumed by cat the first time `-' was used as a file operand and an end-of-file condition
would be detected immediately when `-' was referenced the second time.
ENVIRONMENT VARIABLES
See environ(5) for descriptions of the following environment variables that affect the execution of cat: LANG, LC_ALL, LC_CTYPE, LC_MES-
SAGES, and NLSPATH.
EXIT STATUS
The following exit values are returned:
0 All input files were output successfully.
>0 An error occurred.
ATTRIBUTES
See attributes(5) for descriptions of the following attributes:
+-----------------------------+-----------------------------+
| ATTRIBUTE TYPE | ATTRIBUTE VALUE |
+-----------------------------+-----------------------------+
|Availability |SUNWcsu |
+-----------------------------+-----------------------------+
|CSI |enabled |
+-----------------------------+-----------------------------+
|Interface Stability |Standard |
+-----------------------------+-----------------------------+
SEE ALSO
touch(1), attributes(5), environ(5), largefile(5), standards(5)
NOTES
Redirecting the output of cat onto one of the files being read will cause the loss of the data originally in the file being read. For exam-
ple,
example% cat filename1 filename2 >filename1
causes the original data in filename1 to be lost.
