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

Say I have a text file like:
1

4
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)
After I create printer queues in AIX, I have to append a filter file location within that printers custom file. within lets say test_queue.txt I need to find the row that starts with :699 and then I need to append on the end the string /usr/local/bin/k_portrait.sh.
Now I've gotten the sed... (2 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

PCRE - Perl-compatible regular expressions
PCRE SAMPLE PROGRAM
A simple, complete demonstration program, to get you started with using PCRE, is supplied in the file pcredemo.c in the PCRE distribution.
The program compiles the regular expression that is its first argument, and matches it against the subject string in its second argument.
No PCRE options are set, and default character tables are used. If matching succeeds, the program outputs the portion of the subject that
matched, together with the contents of any captured substrings.
If the -g option is given on the command line, the program then goes on to check for further matches of the same regular expression in the
same subject string. The logic is a little bit tricky because of the possibility of matching an empty string. Comments in the code explain
what is going on.
If PCRE is installed in the standard include and library directories for your system, you should be able to compile the demonstration pro-
gram using this command:
gcc -o pcredemo pcredemo.c -lpcre
If PCRE is installed elsewhere, you may need to add additional options to the command line. For example, on a Unix-like system that has
PCRE installed in /usr/local, you can compile the demonstration program using a command like this:
gcc -o pcredemo -I/usr/local/include pcredemo.c
-L/usr/local/lib -lpcre
Once you have compiled the demonstration program, you can run simple tests like this:
./pcredemo 'cat|dog' 'the cat sat on the mat'
./pcredemo -g 'cat|dog' 'the dog sat on the cat'
Note that there is a much more comprehensive test program, called pcretest, which supports many more facilities for testing regular expres-
sions and the PCRE library. The pcredemo program is provided as a simple coding example.
On some operating systems (e.g. Solaris), when PCRE is not installed in the standard library directory, you may get an error like this when
you try to run pcredemo:
ld.so.1: a.out: fatal: libpcre.so.0: open failed: No such file or directory
This is caused by the way shared library support works on those systems. You need to add
-R/usr/local/lib
(for example) to the compile command to get round this problem.
