Top Forums Shell Programming and Scripting Inserting a line when its length is variable Post 302361166 by nxp on Monday 12th of October 2009 12:10:58 PM

Let me elaborate more on this:

Let's call the file where I want to grab the number from file1 which may look like

Code:
#
#
.
.
 0  56
 3  34
 6  65
 9  98
 12 23
 15 78

So here the number I have to pull out is 15. Then I have to make changes to another file, named file2, i.e. insert a line on the 28th line with following format:

0, 6, 0, 3, 6, 9, 12, 15

Here A=15. Another example can be:

Code:
file1 
#
#
.
.
 0  12
 3  45
 6  78
 9  56
 12 34
 15 90
 18 23
 21 56
 24 8
 27 54
 30 23
 33 12

Then line #28 in file2 will be:

0,12, 0, 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33

Prior to line insertion, file2 is a 50-line text file which will turn into a 51-line file after editing.

Please let me know if it is not yet clear.

Cheers

I just tried the code on Solaris but it gives syntax error:

Syntax error near line 1
bailing out near line 1

Thanks for your help

NAME
paste - paste multiple files together SYNOPSIS
paste [-s] [-d list] file... OPTIONS
-d Set delimiter used to separate columns to list. -s Print files sequentially, file k on line k. EXAMPLES
paste file1 file2 # Print file1 in col 1, file2 in col 2 paste -s f1 f2 # Print f1 on line 1 and f2 on line 2 paste -d : file1 file2 # Print the lines separated by a colon DESCRIPTION
Paste concatenates corresponding lines of the given input files and writes them to standard output. The lines of the different files are separated by the delimiters given with the option -s. If no list is given, a tab is substituted for every linefeed, except the last one. If end-of-file is hit on an input file, subsequent lines are empty. Suppose a set of k files each has one word per line. Then the paste output will have k columns, with the contents of file j in column j. If the -s flag is given, then the first file is on line 1, the second file on line 2, etc. In effect, -s turns the output sideways. If a list of delimiters is given, they are used in turn. The C escape sequences , , \, and are used for linefeed, tab, backslash, and the null string, respectively. PASTE(1)
