hum-tum_tit_for_tat_SIZE = 40

INST = hum-tum

eval TEMP_SIZE="$"${INST}_tit_for_tat_SIZE

it is not evaluating to 40 rather it is evaluating to -tum_tit_for_tat_SIZE
can you pls fix it

i need the temp size value to be 40

farzanj

Try this:

TEMP_SIZE=$(eval echo \$${INST}_tit_for_tat_SIZE)

Sorry don't have shell at this time to test.

i cannot use _ as i'm geeting the value from some file ..

Well, you would need to either substitute using either sed or something.

Try doing

hum\-tum=10

echo ${hum\-tum}

Probably would not work. Then the only solution would be to substitute or get rid of dash
