Full Discussion: How many lines are in a command.
Top Forums UNIX for Dummies Questions & Answers How many lines are in a command. Post 302318476 by #moveon on Thursday 21st of May 2009 03:57:45 PM
Old 05-21-2009
OK, I will explain. There are numerous commands as you know and with the man page you can know about this command. So let us say, I type in man ls for example, or with an option man ls -l, and I get info about this command. Now what I want to do is this: I want to ask the program to tell me how many lines will the man page display about this specific command, in our example ls or with option ls -l. And then again ask about how many specific pair of letters come up in the man pages of this command. So using our example again (ls), I want to ask the programme how many of the letters lm appear in each line of the man pages of this command, for example. To sum up.

I want to know:
1. How many lines about a certain command appear in the man pages when I type man command or man comman -option.
2. How many pair of words appear in each line. So for example to know how many lm appear in each lien of this command in the man pages.

Hope it is a bit clear now. Sorry, if I didn't make it clear before!

script

SCRIPT(1)						    BSD General Commands Manual 						 SCRIPT(1)

NAME

     script -- make typescript of terminal session

SYNOPSIS

     script [-a] [-k] [-q] [-t time] [file [command ...]]

DESCRIPTION

     The script utility makes a typescript of everything printed on your terminal.  It is useful for students who need a hardcopy record of an
     interactive session as proof of an assignment, as the typescript file can be printed out later with lpr(1).

     If the argument file is given, script saves all dialogue in file.	If no file name is given, the typescript is saved in the file typescript.

     If the argument command ... is given, script will run the specified command with an optional argument vector instead of an interactive shell.

     Options:

     -a       Append the output to file or typescript, retaining the prior contents.

     -k       Log keys sent to program as well as output.

     -q       Run in quiet mode, omit the start and stop status messages.

     -t time  Specify time interval between flushing script output file.  A value of 0 causes script to flush for every character I/O event.  The
	      default interval is 30 seconds.

     The script ends when the forked shell (or command) exits (a control-D to exit the Bourne shell (sh(1)), and exit, logout or control-d (if
     ignoreeof is not set) for the C-shell, csh(1)).

     Certain interactive commands, such as vi(1), create garbage in the typescript file.  The script utility works best with commands that do not
     manipulate the screen.  The results are meant to emulate a hardcopy terminal, not an addressable one.

ENVIRONMENT

     The following environment variable is utilized by script:

     SHELL  If the variable SHELL exists, the shell forked by script will be that shell.  If SHELL is not set, the Bourne shell is assumed.  (Most
	    shells set this variable automatically).

SEE ALSO

     csh(1) (for the history mechanism).

HISTORY

     The script command appeared in 3.0BSD.

BUGS

     The script utility places everything in the log file, including linefeeds and backspaces.	This is not what the naive user expects.

     It is not possible to specify a command without also naming the script file because of argument parsing compatibility issues.

     When running in -k mode, echo cancelling is far from ideal.  The slave terminal mode is checked for ECHO mode to check when to avoid manual
     echo logging.  This does not work when in a raw mode where the program being run is doing manual echo.
