Howdy folks,
I am fairly new to scripting but have lost of expirience in c++, pascal, and a few other. I am trying to complete a file search script that is sent a file name containing data to search that is arranged like this

Hi,
I need to use a double grep so to speak. I need to grep for a particular item say BOB and then for each successful result I need to grep for another item say SMITH.
I tried grep "BOB" filename | grep "SMITH"
but it does not seem to work.
I can achieve my desired result using an... (12 Replies)

Hi everybody,
I have a big file with blast results (if you know what this means, otherwise look at it just as a text file with a specific form).
I am trying to extract some ids from within this file, which have certain parameters.
For example, some Of my IDs have the term 'No hit results'... (1 Reply)

Hi guys.
You'd have to excuse me a bit, as I'm a noob. I really try to avoid asking questions and do research for whatever linux issues that may arise.
I am experiencing a long wait for the shell to come up when I ssh or telnet into a Sunos 5.10 environment.
It takes 70 seconds to give me... (12 Replies)

delay
delay(9F) Kernel Functions for Drivers delay(9F)NAME
delay - delay execution for a specified number of clock ticks
SYNOPSIS
#include <sys/ddi.h>
void delay(clock_t ticks);
INTERFACE LEVEL
Architecture independent level 1 (DDI/DKI).
PARAMETERS
ticks The number of clock cycles to delay.
DESCRIPTION
delay() provides a mechanism for a driver to delay its execution for a given period of time. Since the speed of the clock varies among sys-
tems, drivers should base their time values on microseconds and use drv_usectohz(9F) to convert microseconds into clock ticks.
delay() uses timeout(9F) to schedule an internal function to be called after the specified amount of time has elapsed. delay() then waits
until the function is called. Because timeout() is subject to priority inversion, drivers waiting on behalf of processes with real-time
constraints should use cv_timedwait(9F) rather than delay().
delay() does not busy-wait. If busy-waiting is required, use drv_usecwait(9F).
CONTEXT
delay() can be called from user and kernel contexts.
EXAMPLES
Example 1: delay() Example
Before a driver I/O routine allocates buffers and stores any user data in them, it checks the status of the device (line 12). If the device
needs manual intervention (such as, needing to be refilled with paper), a message is displayed on the system console (line 14). The driver
waits an allotted time (line 17) before repeating the procedure.
1 struct device { /* layout of physical device registers */
2 int control; /* physical device control word */
3 int status; /* physical device status word */
4 short xmit_char; /* transmit character to device */
5 };

/* on system console */
14 cmn_err(CE_WARN, "^ 07",
15 (getminor(dev) & 0xf));
16 /* wait one minute and try again */
17 delay(60 * drv_usectohz(1000000));
