Hi Good people :D
How do I check if a directory exists, if it does then carry on rest of the script, otherwise exit.

Hi. I'd like to have an IF-Then-Else statement where I can check to see if a file exists? We have the Bourne Shell by default. I'm looking for the syntax to do something like this:

I need to check whether a file exists and has been changed.
The file should contain a specific string. The file should also have been changed within the last ten seconds.
How do I do that? (3 Replies)

must be less than or equal to If the difference between and inclusive is less than is effectively limited to this difference.
DESCRIPTION
The tunable specifies the minimum process ID (PID) value to generate for new processes. It allows application developers to duplicate an
environment where PID values are large for the purpose of software validation.
This tunable is primarily intended for development environments.
Who is Expected to Change This Tunable?
Anyone interested in software program validation in an environment where PIDs have large values.
Restrictions on Changing
Changes to the tunable are effective immediately. However, any existing processes and their PIDs are not changed.
It is recommended that the system be rebooted after specifying this tunable so that all PIDs in the system will have values in the selected
range.
When Should the Value of This Tunable Be Raised?
Raise this tunable to validate software for tolerance of large PID values in a development environment.
What Are the Side Effects of Raising the Value?
If the difference between and is less than the number of processes allowed to exist simultaneously will be lower than the value of
When Should the Value of This Tunable Be Lowered?
Lower this tunable when the system is meant to be moved from a development to a production environment.
What Are the Side Effects of Lowering the Value?
If the difference between and is less than the number of processes allowed to exist simultaneously will be lower than the value of
What Other Tunable Values Should Be Changed at the Same Time?
It may be desirable to change The tunable should, ideally, be set for the maximum value when validating software which uses PIDs. When
changing it is recommended that the system be rebooted to ensure all processes have PIDs within the desired range.
WARNINGS
All HP-UX kernel tunable parameters are release specific. This parameter may be removed or have its meaning changed in future releases of
HP-UX.
The HP-UX kernel may silently round the selected values for and/or (for example, to the nearest power of 2) in order to accommodate the PID
generation algorithm.
It is recommended that validation of software be carried out with the largest configurable value (1,073,741,567) for the tunable, in con-
junction with the tunable set to something of the same magnitude (for example, 1,000,000,000).
The manpage for (see process_id_max(5)) should be consulted for information about potential application issues with large PID values.
Because session IDs (SIDs) and process group IDs (PGIDs) are the same as the process ID of the session or group leader, an increase in the
minimum PID also increases the minimum SID and PGID.
The system may assign process ID values less than to certain special system processes.
Booting the system with set to a non-zero value may cause the initialization process (aka init) to have a PID of something other than 1.
However, most system utilities and commands will, by default, report the value of the initialization process's PID as 1. For example,
returns 1 if the caller's parent is the initialization process, regardless of its actual PID.
Installation of optional kernel software, from HP or other vendors, may cause changes to tunable parameter values. After installation,
some tunable parameters may no longer be at the default or recommended values. For information about the effects of installation on tun-
able values, consult the documentation for the kernel software being installed. For information about optional kernel software that was
factory installed on your system, see at
