Hi folks,
Our application installation uses "sed" command to append string after specific line or after line number.
Both cases work perfect on Linux but fail on Solaris.
The OS versions are Solaris 9 and Linux Red Hat AS 3.
i.g:
Linux:
-----
file foo.txt
aaa
bbb
ccc
ddd

Have another question that has been eluding me all day.
I have data file I'm trying to reformat so that each line is appended with an ID code, but the ID code needs to update as it searches through the file.
I.e.
----Begin Original Datafile-----
Condition = XXX
Header Line 1

Hi,
I searched the forum for this but couldn't find the answer. Basically I have a line of code I want to insert into a file using sed. The line of code is basically something like "address=1.1.1.1" where 1.1.1.1 is an IP Address that will vary depending on what the user enters. I'll just refer... (4 Replies)

I know this has been asked before but I just can't parse the syntax as explained. I have a set of files that has user information spread out over two lines that I wish to merge into one:

Literally cannot get this one, guys. Single line replacement is simple, but I am not understanding the correct syntax for including a new line feed into the substitution part.
Here's what I got. (Cannot use perl)

set -f
#Start Perms
export HOME=/home/test_user

Hi All,
I'm appending a line before a pattern and after another pattern(;) but omitting the first pattern - same as if comes duplicates before the second pattern.
Also, I'm adding a word before the first pattern -
Here is my file
select blah blah
hello
select blah blah

grep
GREP(1) General Commands Manual GREP(1)NAME
grep - search a file for a pattern
SYNOPSIS
grep [ option ... ] pattern [ file ... ]
DESCRIPTION
Grep searches the input files (standard input default) for lines (with newlines excluded) that match the pattern, a regular expression as
defined in regexp(6). Normally, each line matching the pattern is `selected', and each selected line is copied to the standard output.
The options are
-c Print only a count of matching lines.
-h Do not print file name tags (headers) with output lines.
-i Ignore alphabetic case distinctions. The implementation folds into lower case all letters in the pattern and input before interpre-
tation. Matched lines are printed in their original form.
-l (ell) Print the names of files with selected lines; don't print the lines.
-L Print the names of files with no selected lines; the converse of -l.
-n Mark each printed line with its line number counted in its file.
-s Produce no output, but return status.
-v Reverse: print lines that do not match the pattern.
Output lines are tagged by file name when there is more than one input file. (To force this tagging, include /dev/null as a file name
argument.)
Care should be taken when using the shell metacharacters $*[^|()= and newline in pattern; it is safest to enclose the entire expression in
single quotes '...'.

Exit status is null if any lines are selected, or non-null when no lines are selected or an error occurs.
