I need help one more time
Something very simple in fact but i do not know how the if else and while tests work in shell bash...
I use a line like that, the same that i use in C-C++...
while (sed -n '$jp' ls_mpg.txt && $ok == 0)
if (sed -n '$jp' ls_mpg.txt == sed -n '$in' ls_mp4.txt) then
$ok = 1
does this ("sed -n '$jp' ls_mpg.txt && $ok == 0") works?
Thank you for your help
