Building an environment file

[Manuales]

Hi, i'm biulding an environment file named:
.environment

and it contains the following:
dirs="scripts scripts-log menu monitoring processes functions scripts main-log"
for minuscula in `echo $dirs`
do
mayuscula=`echo $minuscula | tr "[:lower:]" "[:upper:]"`
if [[ $minuscula = "scripts-log" ]]
then
${minuscula}="${HOME}/SCRIPTS/${1}/LOG"
else
${minuscula}="${HOME}/$mayuscula"
fi
done
mails="dm@yahoo.com.mx hola@yahoo.com.mx"
hn-server=$(hostname)


but the output the following is:
$ . ./.environment 0001-Alert-Temperature
ksh: scripts=/home/DRTEAM01/SCRIPTS: not found
ksh: scripts-log=/home/DRTEAM01/SCRIPTS/0001-Alert-Temperature/LOG: not found
ksh: menu=/home/DRTEAM01/MENU: not found
ksh: monitoring=/home/DRTEAM01/MONITORING: not found
ksh: processes=/home/DRTEAM01/PROCESSES: not found
ksh: functions=/home/DRTEAM01/FUNCTIONS: not found
ksh: scripts=/home/DRTEAM01/SCRIPTS: not found
ksh: main-log=/home/DRTEAM01/MAIN-LOG: not found
ksh: hn-server=torpdbp: not found

Why does appears that mistake?
it supposes that it must shows the assigned, does not it?

Please help.
Thanks.

The lines:

${minuscula}="${HOME}/SCRIPTS/${1}/LOG"

${minuscula}="${HOME}/$mayuscula"

are incorrect. Assignments for variable must list the variable name, not the contents. When you put $ or ${} around a variable name, the shell replaces the variable name with the contents of the variable. The lines should read:

minuscula="${HOME}/SCRIPTS/${1}/LOG"

minuscula="${HOME}/$mayuscula"

Hi,

in addition to Bills correct solution:
Having set
dirs="scripts scripts-log menu monitoring processes functions scripts main-log"

... there is no need to use such a construction:

for minuscula in `echo $dirs`
do ...
done

Better and simpler just use
for minuscula in $dirs
do ...
done

Hi ..
but i need to put $minusucula because every time it must be:

scripts="${HOME}/SCRIPTS"
scriptslog="${HOME}/SCRIPTS/${1}/LOG"
menu="${HOME}/MENU"
monitoring="${HOME}/MONITORING"
processes="${HOME}/PROCESSES"
functions="${HOME}/FUNCTIONS"
scripts="${HOME}/SCRIPTS"
mainlog="${HOME}/MAINLOG"

it's because the contents of the variable is the value of "dirs" ....

i can not put :
minuscula="${HOME}/$mayuscula"

i need to put
$minuscula="${HOME}/$mayuscula"

where the first time minuscula would be:
minuscula=scripts
scripts=/home/DRTEAM01/SCRIPTS

minuscula=scriptslog
scriptslog=/home/DRTEAM01/SCRIPTS//LOG

minuscula=menu
menu=/home/DRTEAM01/MENU

and go on ....

what could i built this lines???

Regards.

Hi,

to get a variable name depending on a variable, you could use

for minuscula in $dir
do
eval $minuscula=$dir
...
done

BUT: this will NOT work for the values
dir=main-log
dir=hn-server
since a variable name cannot contain a dash '-'.

Better use arrays and access the pairs of the requested values through equal indices.
Example:

set -A dir scripts scripts-log menu monitoring processes functions scripts main-log
typeset -i idx=0 asize=0

set -A mayuscula $(typeset -u mayus
for mm in ${dir[*]}
do
mayus=$mm
if [[ $mm = "scripts-log" ]]
then print ${HOME}/SCRIPTS/${1}/LOG
else print ${HOME}/$mayus
fi
done
)

asize=${#dir[*]}
while [ idx -lt asize ]
do
print dir=${dir[idx]} mayuscula=${mayuscula[idx]}
((idx+=1))
done

The latter is just an output of the coresponding array values - put your code here.
