Full Discussion: Obtaining A Process ID (PID)
Top Forums UNIX for Advanced & Expert Users Obtaining A Process ID (PID) Post 9414 by 1cuervo on Friday 26th of October 2001 09:33:55 AM

Sorry for the double post.

How does the "pid=$!" command reveal the value of the ! variable for the process invoked in the "emacs file.txt&" command?

Is the "pid=$!" command issued separately to the emacs command, or is it on the same command line?

Essentially, all I want to do is 'echo' the value of the PID for each program execution command.

Could you please show me an example?

Many thanks.

emacs

emacs(1)						      General Commands Manual							  emacs(1)

NAME

       emacs, xemacs - emacs editor

DESCRIPTION

       The  emacs  software is unsupported software that is provided as part of Tru64 UNIX.  Compaq will fix problems in this unsupported software
       only if they are specific to Tru64 UNIX. Compaq will not fix problems that are integral to the software itself or that occur when the  com-
       ponent is used on UNIX systems other than Tru64 UNIX. Compaq will not add functionality to this software.

       Except for this reference page, other reference pages that Tru64 UNIX supplies for emacs are passed through without changes.  The reference
       pages distributed as part of this software are available in the directories  /usr/share/doclib/annex/man/man[1-9].   You  should  use  this
       directory stem in the man command or add it to the MANPATH environment variable to make these files available to the man command.

									  Note

       Compaq  is  not	responsible  for the content or quality of reference pages and other documents installed under the /usr/share/doclib/annex
       directory  and  does  not  revise  this	material  in  response	to  customer  problem  reports.  Reference  pages  installed   under   the
       /usr/share/doclib/annex/man directory are not available from Compaq in book form; for example, they are not included in the reference manu-
       als that you receive when you order the Tru64 UNIX documentation set as hard copy books.

       Problems related to the content or quality of any documentation installed in the /usr/share/doclib/annex directory tree should be  sent	to
       the developers of the documentation.

       The format for changing the search path with the man command is: man -P /usr/share/doclib/annex/man [section] title...

       If  you	are  using  the  Bourne,  Korn,  or  POSIX  shells,  use  the following command sequence to modify your environment: MANPATH=$MAN-
       PATH:/usr/share/doclib/annex/man export MANPATH

       If you are using the C shell, enter the command: setenv MANPATH `echo $MANPATH`:/usr/share/doclib/annex/man

       See the reference pages for the man(1) command for additional information on the search path used to locate files.

       The reference pages associated with this product are not included in the whatis data base created by the catman	command.   Therefore,  the
       man -k and apropos commands will not locate reference pages included with this product.
