Using the command :
echo $eup_terminal_code | tr -s 'mil vrn qcm' 'mci pql qcm'
it works,but this translation changes depending on the system.

I'd like to define the following variables ,one for each system :

mil22h_from='mil vrn frl'
mil22h_to='mci vci fci'

czhs0362_from='mil vrn flr'
czhs0362_to='mot vot fot'

I'd like to use a command like this :
echo $eup_terminal_code | tr -s uname-n_from uname -n_to
but it doesn't work.

tks in advance

You are not using the right command. tr command replaces character by character and not a strying by another string

Use sed command

Code:

echo $eup_terminal_code | sed "s/uname-n_from/uname -n_to/"

The result I'd like to obtain is the following :
depending on the system name 'uname -n' a variable content should be replaced
with another string,example :
for mil22h system mil with moc flr with foc vrn with moc
for mil21h system mil with mac flr with fac vrn with vac
tks in advance

Let's say that I'd like to change a content of variable defined on change_from with the content defined on change_to,example mil with moc ,flr with foc :
change_from="mil:flr:vrn"
change_to="moc:foc:voc"
how can i do this ?

Code:

echo 'mil22h system mil with moc flr with foc vrn with moc' |sed 's/mil/moc/g;s/flr/foc/g;s/vrn/moc/g'

or, per your later post:

Code:

echo 'mil22h system mil with moc flr with foc vrn with voc' |sed 's/mil/moc/g;s/flr/foc/g;s/vrn/voc/g'

this will work under the condition of "if 'uname -n' == mil22h ..............
But is there a way to solve this issue without change the source,I mean using only variables : example
mil22h_from(system name)="mil:flr:vrn"
mil22h_to(system name)="moc:foc:voc"
mil06h_from="mil:flr:vrn"
mil06h_to="mac:fac:vac"
I'd like to avoid to change the sourec and in case os a new server only two new variables will be necessary :
new system name_from="xxx:xxx:xxx:"
new system name_to="yyy:yyy:yyy"
Depending on the result of "uname -n" the command will choose the right variable
tks all of you in advance for your help
