splitting and assigning

splitting and assigning

[meino.cramer]

Hi,

I have a looooooong list, whgich consists
of a 32 character long checksum (from md5sum),
two spaces and a absolute path with the checksummed file.

I want to split each line into two parts:
the checksum and the path/file and assign each part 
to a separate variable.

I tried to put this into a one-liner and failed using
${(s:  :)line}.

How can I do that?

Best regards and have a nice weekend!
Best regards,
mcc

Use the right tool for the job. At some point you need to consider
switching to a different language. In Python the task is trivial. This is
from an iPython interactive session:

In [1]: data = ['md5sum#1  pathname#1', 'md5sum#2  pathname#2']

In [2]: data = [d.split() for d in data]

In [3]: data
Out[3]: [['md5sum#1', 'pathname#1'], ['md5sum#2', 'pathname#2']]

In [4]: checksums, pathnames = zip(*data)

In [5]: checksums
Out[5]: ('md5sum#1', 'md5sum#2')

In [6]: pathnames
Out[6]: ('pathname#1', 'pathname#2')

another method:  if your data is in an array, cycle through the array.

ds=( ${(f)${"$(< your_data_file )"}} )
for l in ${ds} ; do e=( ${=l} ) ; echo "e1:  ${e[1]}, e2:  ${e[2]}" ; done
