Jupyter run Bash command without printing output
Is there a way to run command line commands in Jupyter without the cell output?
e.g.
!wget http://files.fast.ai/data/dogscats.zip -P ./data/
without printing the process in my cell?
bash jupyter

the oldest trick works:
!wget ... >/dev/null 2>&1
or with --err
option:
In [1]: %%bash --err null
...: wget ...
this actually stores the stderr
output into the variable null
.

great! to provide context: the null device is a device file that discards all data written to it but reports that the write operation succeeded. This device is called /dev/null on Unix and Unix-like systems.
