I tried this on an old version of sed on NCR Unix MP-RAS:
This file (file1):
becomes this (file2):
Now, I tried to port this sed script to GNU sed v.4.1.5 on RHEL5. Using the same script:
my output looks like this:
I tried awk instead of sed...
but get the same results from both platforms (MP-RAS appends to end of line, RHEL overtypes first 3 chars of each line).
Any ideas why? Any ideas how to fix - I am running out of ideas.
Anyone know how to use SED to append a comma to the end of each line
example:
field1,field2,field3,field4

Say I have a text file like:

How would I use ksh to put the number '2' into the second line of that file? I'm using OpenBSD so the sed syntax might be a bit different (I have no idea how to use sed, though) (4 Replies)

I've scoured the internet with mixed results. As an amateur I turn to the great minds here.
I have a text file of 80 or so lines. I want to add ".pdf" to the end of each line. (For now that's it)
Most of the internet points toward using "sed". I don't know coding but can figure things out... (4 Replies)

I have some html with hrefs that contain local links to pdf filenames. These filenames should have standardised names, i.e. there should be a label prior to the ".pdf" filename suffix. There can be many of these links on a single line of text and some may already have the label. For example

cat
CAT(1) BSD General Commands Manual CAT(1)NAME
cat -- concatenate and print files
SYNOPSIS
cat [-belnstuv] [file ...]
DESCRIPTION
The cat utility reads files sequentially, writing them to the standard output. The file operands are processed in command-line order. If
file is a single dash ('-') or absent, cat reads from the standard input. If file is a UNIX domain socket, cat connects to it and then reads
it until EOF. This complements the UNIX domain binding capability available in inetd(8).
The options are as follows:
-b Number the non-blank output lines, starting at 1.
-e Display non-printing characters (see the -v option), and display a dollar sign ('$') at the end of each line.
-l Set an exclusive advisory lock on the standard output file descriptor. This lock is set using fcntl(2) with the F_SETLKW command.
If the output file is already locked, cat will block until the lock is acquired.
-n Number the output lines, starting at 1.
-s Squeeze multiple adjacent empty lines, causing the output to be single spaced.
-t Display non-printing characters (see the -v option), and display tab characters as '^I'.
-u Disable output buffering.
-v Display non-printing characters so they are visible. Control characters print as '^X' for control-X; the delete character (octal
0177) prints as '^?'. Non-ASCII characters (with the high bit set) are printed as 'M-' (for meta) followed by the character for the
low 7 bits.
EXIT STATUS
The cat utility exits 0 on success, and >0 if an error occurs.
EXAMPLES
The command:
cat file1
will print the contents of file1 to the standard output.
The command:
cat file1 file2 > file3
will sequentially print the contents of file1 and file2 to the file file3, truncating file3 if it already exists. See the manual page for
your shell (e.g., sh(1)) for more information on redirection.
The command:
cat file1 - file2 - file3
will print the contents of file1, print data it receives from the standard input until it receives an EOF ('^D') character, print the con-
tents of file2, read and output contents of the standard input again, then finally output the contents of file3. Note that if the standard
input referred to a file, the second dash on the command-line would have no effect, since the entire contents of the file would have already
been read and printed by cat when it encountered the first '-' operand.

Rob Pike, "UNIX Style, or cat -v Considered Harmful", USENIX Summer Conference Proceedings, 1983.
STANDARDS
The cat utility is compliant with the IEEE Std 1003.2-1992 (``POSIX.2'') specification.
The flags [-belnstv] are extensions to the specification.
HISTORY
A cat utility appeared in Version 1 AT&T UNIX. Dennis Ritchie designed and wrote the first man page. It appears to have been cat(1).
BUGS
Because of the shell language mechanism used to perform output redirection, the command ``cat file1 file2 > file1'' will cause the original
data in file1 to be destroyed!
The cat utility does not recognize multibyte characters when the -t or -v option is in effect.
