Error Exporting Value of a Variable as a Variable
Here's how;
Say;
I have a variable VAR which contains something like MY_DIR=/apphome/some/mydir.

What I want is I want to export VAR so that it will vitually export MY_DIR. Please suggest me?

Error Additional Info
I'm using ksh. I did like this
Code:
export $VAR

but it keeps on saying "is not an identifier"

The syntax is export VAR without a dollar sign.

Thanks! But echoing $MY_DIR returns nothing.

>export VAR=/dev/null
while using this environmental variables you have to use $VAR.

i am not clear some places i saw that assigning a env var with colon ':'
export PATH=/usr/bin:/usr/ucb:/etc:/usr/sbin:.:/usr/platform/sun4u/sbin

here you can find : and a . and again :
could some one explain this

The colon doesn't matter from the shell's point of view at all. When the value of the variable contains multiple fields, you need to decide on a field separator. For variables which contain lists of paths, the colon is often picked as the field separator.

Please start a new thread unless your question is a direct follow-up to the current topic.

Actually, there is nothing to do with the path. I am making a shell script that reads values from a properties file. So, in properties file, I put like that;
MY_DIR=/apphome/some/mydir. I read them with egrep. I got the whole string and I don't know what to do the rest Smilie. Any alternative? (Sorry if my post changes to another topic) I really need urgently.
