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

Syntax error near line 1
bailing out near line 1

Thanks for your help

NAME
mv - move or rename files SYNOPSIS
mv [ -i ] [ -f ] [ - ] file1 file2 mv [ -i ] [ -f ] [ - ] file ... directory DESCRIPTION
Mv moves (changes the name of) file1 to file2. If file2 already exists, it is removed before file1 is moved. If file2 has a mode which forbids writing, mv prints the mode (see chmod(2)) and reads the standard input to obtain a line; if the line begins with y, the move takes place; if not, mv exits. In the second form, one or more files (plain files or directories) are moved to the directory with their original file-names. Mv refuses to move a file onto itself. Options: -i stands for interactive mode. Whenever a move is to supercede an existing file, the user is prompted by the name of the file followed by a question mark. If he answers with a line starting with 'y', the move continues. Any other reply prevents the move from occur- ring. -f stands for force. This option overrides any mode restrictions or the -i switch. - means interpret all the following arguments to mv as file names. This allows file names starting with minus. SEE ALSO
cp(1), ln(1) BUGS
If file1 and file2 lie on different file systems, mv must copy the file and delete the original. In this case the owner name becomes that of the copying process and any linking relationship with other files is lost. 4th Berkeley Distribution April 29, 1985 MV(1)
