incrementing the variable name along with the data?
Hello folks.
I am trying to increment my variable names to match a counter that is to be used later on...
Basically, i have a for loop that lists directories (for example TEST_OS DVP_OS PROD_OS ) but this loop is not static, it may contain 3 directory once and the next run 5 directories.
I then, want to assign "selection1" to TEST_OS, "selection2" to DVP_OS and "selection3" to PRD_OS. Again, those are not static...
Here is the code i have for now, but the "combining" of variables is not working... (selection$counter=$i) What i want, is that the variable selection1=TEST_OS and so forth...
Code:
BKPSETS=`ls -altr /etc/workdir/ | grep $OS | awk '{print $9}'`
counter=1
for i in $BKPSETS
do
echo $counter "-" $i
selection$counter=$i
echo $selection
counter=`expr $counter + 1`
done
read CHOICE
if [[ $CHOICE -ge $COUNTER ]]
then
echo "No such choice available. Quitting!"
exit 1
else
echo "You've selected option $CHOICE"
fi
I have 3 columns in an excel sheet.
c1 c2 c3
EIP_ACCOUNT SMALL_TS_01 select A.* from acc;
All the above 3 col shoud be passed a variable in the unix code.

nice
NICE(1) BSD General Commands Manual NICE(1)NAME
nice -- execute a utility at an altered scheduling priority
SYNOPSIS
nice [-n increment] utility [argument ...]
DESCRIPTION
The nice utility runs utility at an altered scheduling priority, by incrementing its ``nice'' value by the specified increment, or a default
value of 10. The lower the nice value of a process, the higher its scheduling priority.
The superuser may specify a negative increment in order to run a utility with a higher scheduling priority.
Some shells may provide a builtin nice command which is similar or identical to this utility. Consult the builtin(1) manual page.
ENVIRONMENT
The PATH environment variable is used to locate the requested utility if the name contains no '/' characters.
EXAMPLES
Execute utility 'date' at priority 5 assuming the priority of the shell is 0:
nice -n 5 date
Execute utility 'date' at priority -19 assuming the priority of the shell is 0 and you are the super-user:
nice -n 16 nice -n -35 date
DIAGNOSTICS
If utility is invoked, the exit status of nice is the exit status of utility.
An exit status of 126 indicates utility was found, but could not be executed. An exit status of 127 indicates utility could not be found.
SEE ALSO builtin(1), csh(1), idprio(1), rtprio(1), getpriority(2), setpriority(2), renice(8)COMPATIBILITY
The traditional -increment option has been deprecated but is still supported.
STANDARDS
The nice utility conforms to IEEE Std 1003.1-2001 (``POSIX.1'').
HISTORY
A nice utility appeared in Version 4 AT&T UNIX.
BSD June 6, 1993 BSD
