Dear all,
How can we know in a KornShell script reading a value from the standard input, that the entered value is the newline character? because as far as I know we cannot use \n for pattern matching. For example:
#!/bin/ksh
print -n "enter your value: "
read VALUE
if ]

Hi, I have written a script that allows me to repetitively play a music file $N times, which is specified through user input. However, if I want to exit the script before it has finished looping $N times, if I use CTRL+c, I have to CTRL+c however many times are left in order to complete the loop.... (9 Replies)
I am trying to allow a user to enter in text and then store that text in a variable $gene to run in an awk command in which those values are used to run some calculations. I am getting syntax errors however, when I try. Thank you :).

lamnodes
LAMNODES(1) LAM TOOLS LAMNODES(1)NAME
lamnodes - Resolve LAM node/CPU notation to Unix hostnames.
SYNOPSIS
lamnodes [-chin] [where]
OPTIONS -c Suppress printing the CPU count for each node.
-h Print the command help menu.
-i Print IP addresses (instead of IP names)
-n Suppress printing CPU count for each node
DESCRIPTION
The lamnodes command is used to resolve LAM node/CPU nomenclature to Unix hostnames. It can be used to determine the current running con-
figuration of the LAM/MPI run-time environment, and generate a boot schema that can be used to launch LAM in the future.
By default, lamnodes will print out the node number, default IP name, CPU count, and per-node flags for each node in the running LAM.
gethostbyaddr(3) is used to obtain default hostnames. If gethostbyaddr(3) fails, the IP number is displayed instead.
This command can be used by setup shell scripts (and the like) to determine information from a currently-running LAM universe. For exam-
ple, use lamnodes to resolve particular CPUs and/or nodes to specific unix hostnames. In a batch environment, lamnodes can be used to
determine which CPUs share a common node (note that MPI_GET_PROCESSOR_NAME can be used for a similar effect in an MPI program).
lamnodes also shows per-node flags. Currently defined flags are:
origin The node where lamboot was executed.
this_node The node where lamnodes is running.
no_schedule The node will not be used to run MPI and serial processes when N and C are used to mpirun and lamexec.
EXAMPLES
lamnodes N -n
Display IP names and CPU counts for all nodes. This output can be saved and later used with lamboot(1).
lamnodes C -n -c
Display the IP name of the nodes containing each CPU, and suppress the LAM node number and CPU count. This output can be saved and
later used with lamboot(1).
