If/then/fi and variable
Hi everyone,

I have a question. I have this script :

Code:
for f in *.faa
{
echo $f
nmb=0
num_occur_HVE=0
num_occur_REY=0
base=`basename $f .faa`
num_occur_HVE=`sed -n '/'"$base"'/p' LAL.vs.HVE.csv | awk 'BEGIN{FS=";"}{print $(NF-3)}'`
num_occur_REY=`sed -n '/'"$base"'/p' LAL.vs.REY.csv | awk 'BEGIN{FS=";"}{print $(NF-3)}'`
if [ $num_occur_HVE -eq 0 ]; then ( ((nmb++)); echo $nmb ) fi
if [ $num_occur_REY -eq 0 ]; then ( ((nmb++)); echo $nmb ) fi
echo $nmb
}

echo $nmb from INSIDE the IF/THEN/FI is the right one (1 or 2 or both)
echo $nmb from OUTSIDE the IF/THEN/FI is always 0 (so, the wrong one)

Obviously, I need the one outside the IF loop to be accurate...

I need the incrementation, because I want to know if the equality is found in one of my file or both (or none).

Any idea ?
Thank you !!!

Hi.

From the bash man page:
Quote:
(list) list is executed in a subshell environment
Remove the outer brackets after then and before fi (and add a semi-colon):

Code:
if [ $num_occur_HVE -eq 0 ]; then ((nmb++)); echo $nmb; fi
if [ $num_occur_REY -eq 0 ]; then ((nmb++)); echo $nmb; fi
