Is this a homework assignment? ==> this is not homework assignment .
Is my_string a constant, or is it a parameter to your script? ==> my_string is a constant
What have you tried to solved this problem? ==> sorry , I am new to script writing . I tried read something but still not find any idea.
Are the blank line and the this is a testing file in file1 ? ==> in file1 , there are blank line and have other line not begins with "A" or "B" .
Are the A and B lines always in that order? ==> yes , A then B
Are there ever other lines between the A and B lines? ==> No other lines.
Instead of generating the file2 after each time run the script , is it possible to append the new lines to file2 ? for example , if there is the following new lines in file1 .
Code:
A iiiii
B jjjjj
then append the following new line to file2 rather than re-generate file2 ?
I have an input file which looks like this:
601 a
602 a
603 a
601 b
610 c
615 c
603 d
601 d
612 d

601 a 602 603
602 a 601 603
603 a 601 602
601 b
610 c 615

Write a script named time that displays the time in standard 12-hour format, rather than 24-hour format. Allow the user to give a -m option to get 24-hour format. For example:
> date
Sun Feb 10 10:56:50 CST 2008
> time
10:56 AM
> date
Sun Feb 10 21:57:07 CST 2008

comm
COMM(1) BSD General Commands Manual COMM(1)NAME
comm -- select or reject lines common to two files
SYNOPSIS
comm [-123i] file1 file2
DESCRIPTION
The comm utility reads file1 and file2, which should be sorted lexically, and produces three text columns as output: lines only in file1;
lines only in file2; and lines in both files.
The filename ``-'' means the standard input.
The following options are available:
-1 Suppress printing of column 1, lines only in file1.
-2 Suppress printing of column 2, lines only in file2.
-3 Suppress printing of column 3, lines common to both.
-i Case insensitive comparison of lines.
Each column will have a number of tab characters prepended to it equal to the number of lower numbered columns that are being printed. For
example, if column number two is being suppressed, lines printed in column number one will not have any tabs preceding them, and lines
printed in column number three will have one.
The comm utility assumes that the files are lexically sorted; all characters participate in line comparisons.
ENVIRONMENT
The LANG, LC_ALL, LC_COLLATE, and LC_CTYPE environment variables affect the execution of comm as described in environ(7).
EXIT STATUS
The comm utility exits 0 on success, and >0 if an error occurs.
SEE ALSO cmp(1), diff(1), sort(1), uniq(1)STANDARDS
The comm utility conforms to IEEE Std 1003.2-1992 (``POSIX.2'').
The -i option is an extension to the POSIX standard.
HISTORY
A comm command appeared in Version 4 AT&T UNIX.
