list and export strings in a file

Shell Programming and Scripting
1

Hi all,

I have a file looks something like this:

aaaa
bbbbbb
ccc
dddddddd

I will like a script that can
echo line1
export line1 as env variable
echo line2
export line2 as env variable
etc
etc

Thanks in advance

for ELE in `grep -v "^~" infile`; do
   echo "${ELE}"
   export "${ELE}"
done

Of course you should think about assigning variable names in your file.

Hi Zaxxon,

Thanks for the fast response...
It will be fine if I can set it as a variable in a file, but what I'm after is the following:

Say I have a text file named file.text that has the following entries:
aaaa
bbb
cc
d

What I want to do is to list them as a menu in format:

1) aaaa
2) bbb
3) cc
4) d

and at the same time set them as variables

sid1 = aaaa
sid2 = bbb
etc
etc

Can you please help with this, I have the following but it doesn't work like I want it to.

num = 'cat file.txt | wc -l'
for ELE in `grep -v "^~" file.txt`
do
for (( i = 0; i < num; i++))
do
echo "$i) ${ELE}"
sid $i="${ELE}"
done
done

The output from this gives:
1) aaaa
1) bbb

and doesn't set the variables correctly either.

Thanks in advance

If your shell has select then perhaps this is sufficient.

select ELE in `cat file.txt`; do
  echo $ELE
done

(Type ctrl-D to escape from the prompt.)
