for i in
glob.glob('/sys/kernel/debug/ieee80211/phy*/iwlagn/data/continuous_tx'):
with open(i, 'w') as f:
print >>f, cont_tx
work perfectly.
But following get error like:
print >>f, cont_tx
IOError: [Errno 28] No space left on device
Apparently the harddisk where you stored the file is full?
Likely a misinterpretation of the error. I'm guessing either one
needs to be root to write to this [likely virtual] file, or a
member of an associated group. It would help to have the output of
bash$ whoami
bash$ id
and
bash$ ls -lsF
/sys/kernel/debug/ieee80211/phy*/iwlagn/data/continuous_tx
I'd be particularly interested in the group association and the
permission bits.
