bash - Escape sequence not working in python script run from a shell script -


i have shell script needs run python script. python script may passed argument.

python pgm32.py $args

but when argument passed has escape sequence or if encase in quotes, python scripts not recognize it.

for instance args contains "open drive" or open\ drive python script's sys.argv=['pgm32.py', '"open', 'drive"'] or sys.argv=['pgm32.py', '"open', 'drive"'] respectively.

but when call python script directly command line, , pass argument "open drive" or open\ drive, script's sys.arv=['pgm32.py', 'open drive']

how can fix issue?

it's quite simple. quote argument in shell command:

$ python pgm32.py "$args"

you did yourself:

but when call python script directly command line, , pass argument "open drive" or open\ drive, script's sys.arv=['pgm32.py', 'open drive']

which worked because in these lines protected space shell word splitting; in other examples didn't. shell , has nothing python.
