i want a command that will output any one of this lines based upon the number i pass it as parameter.
eg.
$ ./script file1 2 (script being the command)
Using either of these two methods within a script would be easy, using positional parameters
Take a look at your shells manual page to learn more about positional parameters and passing arguments to scripts.
You could also implement error checking by ensuring that the file passed exists (look at the "test" or "[" builtins/commands)....
A typical line looks like this...
) ENGINE=MyISAM DEFAULT CHARSET=utf8 COLLATE=utf8_bin AUTO_INCREMENT=129 COMMENT='Compiled E-Mails';I want to remove DEFAULT CHARSET= and COLLATE= after resetting AUTO_INCREMENT=0
I do not want to change the engine and comment. (7 Replies)
Hi
I am using "grep" command to get certain pattern out of the file:
PNUM=34

#34 * 2297 * 410 * 964 * * 4352

Is there a way to retrieve the section of the above output without #34 so the output would look like this:... (3 Replies)

getopt
getopt(1) General Commands Manual getopt(1)Name
getopt - parse command options
Syntax
set - - getopt optstring $*
Description
The command breaks up options in command lines for easy parsing by Shell procedures and checks for legal options. The optstring option
letters are recognized if a letter is followed by a colon, the option expects an argument which may or may not be separated from it by
white space. For further information, see
The special option, specified by two minus signs (- -), delimits the end of the options. If the delimiters are used explicitly, recognizes
it; otherwise, generates it. In either case, places the delimiter at the end of the options. The positional parameters ($1 $2 ...) of the
shell are reset so that each option is preceded by a single minus sign (-) and is in its own positional parameter; each option argument is
also parsed into its own positional parameter.
Examples
The following code fragment shows how you can process the arguments for a command that can take the options a or b, as well as the option
o, which requires an argument:
#!/bin/sh5
set -- getopt abo: $*
if [ $? != 0 ]
then
echo $USAGE
exit 2
fi
for i in $*
do
case $i in
-a | -b) FLAG=$i; shift;;
-o) OARG=$2; shift 2;;
--) shift; break;;
esac
done
This code accepts any of the following as equivalent:
cmd -aoarg file file
cmd -a -o arg file file
cmd -oarg -a file file
cmd -a -oarg -- file file
Diagnostics
The command prints an error message on the standard error when it encounters an option letter not included in optstring.
