How can I make a script for run another script

bash is not C, for, if and [ are all commands and require whitespace to separate them from other words.

Use

cd /Users/KanZ/Desktop/Project/Test/Model/Object
for file in *.obj
do
    h=${file%.obj}.h
    ./obj2opengl.pl "$file"
    mv "$h" ../Header
done

See the bash manual to explain the ${file%.obj} part

If you want to count, don't keep track of leading zeroes manually, use printf:

max_width=${#end}
for ((i=$start; i<=$end; i++)); do
    printf -v n "%0*d" $max_width $i
    obj="A$n.obj"
    h="A$n.h"
    ./obj2opengl.pl "$obj" 
    mv "$h" ../Header
done

if[$c > 9] then
   b++

I think here is the syntax error. [ is a command in shell, it takes one or more args, and the last arg must be [, so you must use space to seperate the command and args, and also need space between if and [.

Another error, shell do not support c style ++， you can use b=$[b+1].

Here is the correct code:

cd /Users/KanZ/Desktop/Project/Test/Model/Object
start=1
a=0
b=0
c=1
n=$(find . -name "*.obj" | wc -l)
end=$(($n));
for((i=$start;i<=$end;i++))
do
   ./obj2opengl.pl "A${a}${b}${c}.obj"
   mv "A${i}.h" /Users/KanZ/Desktop/Project/Test/Model/Header
   c=$[c+1]
if [ $c > 9 ] then
   b=$[b+1]
   c=0
fi
if [ $b > 9 ] then
   a=$[a+1]
   b=0
   c=0
fi
done

If I adapt my code by using if statement , How can I fix this code for the right syntax For example:

cd /Users/KanZ/Desktop/Project/Test/Model/Object
start=1
a=0
b=0
c=1
n=$(find . -name "*.obj" | wc -l)
end=$(($n));
for((i=$start;i<=$end;i++))
do
   ./obj2opengl.pl "A${a}${b}${c}.obj"
   mv "A${i}.h" /Users/KanZ/Desktop/Project/Test/Model/Header
   c++
if[$c > 9] then
   b++
   c=0
fi
if[$b>9] then
   a++
   b=0
   c=0
fi
done

cd /Users/KanZ/Desktop/Project/Test/Model/Object

find . -name "A*.obj" -exec obj2opengl.pl {} \;
find . -name "A*.h" -exec mv {} /Users/KanZ/Desktop/Project/Test/Model/Header \;
