Dynamic variable assignment
Hi All,
I have the below scenario:
A file test.cfg with three fields>>
DATA1 DATA2 DATA3
In the script I need to assign each of the fields to variables. The number of fields will not be constant (this case we have three). Im trying to do something like this:
NUM=1
OUT_DAT_NO=3
while [ $NUM -le $OUT_DAT_NO ]
do
OUT_DAT$NUM=`cat test.cfg | awk '{print $NUM}'`
NUM=`expr $NUM + 1`
done
The output should be like this:
OUT_DAT1=DATA1
OUT_DAT2=DATA2
OUT_DAT3=DATA3
Is there any way of doing this in bash?
Thanks,
D

runlim
RUNLIM(1) General Commands Manual RUNLIM(1)
NAME
runlim - a program to run benchmarks
SYNOPSIS
runlim [ options ...] command [ arguments ...]
DESCRIPTION
run is a tool that can be used to run and control benchmarks. It executes a given command with (optional) arguments, samples resource
usage during the run, and kills the process (and its child processes) if a certain time and/or space limit is exhausted.
Every 100 milliseconds, runlim takes a sample of the program's resource utilization, and logs status information to stderr every second.
Optionally, the status can be logged to a file.
Multi-threaded programs can be limited by setting a wall clock timeout. runlim follows the time accumulation scheme of GNU time for multi-
threaded programs and programs that spawn multiple child-processes: time spent in each thread/child is summed up, unless you are only
interested in walk clock time.
OPTIONS
runlim accepts the following options:
-h, --help
Show summary of options.
--version
Show version of program.
-o FILE, --output-file=FILE
Overwrite or create FILE for output logging.
-s NUM, --space-limit=NUM
Set space limit to NUM megabytes.
-t NUM, --time-limit=NUM
Set time limit to NUM seconds.
-r NUM, --real-time-limit=NUM
Set real time limit to NUM seconds.
-k, --kill
Propagate signals.
SEE ALSO
time(1), timelimit(1), timeout(1), time(7).
