I get " ERROR:root:list index out of range" error if the file is
not found in any of the machine , I dont have a trackback back
def check_file():
"""
333333333333333333333333333333333333333333333333333333333333333333333333333333333333
Run the command parallel on all the machines , if there is a
file named /tmp/file2.txt extract file2.txt
"""
global filename
file = ''
cmd = ("run_al_paral 'ls -al %s'" % (filename))
print(cmd)
stdout, stderr, exitcode = run(cmd)
print(stdout)
lines = stdout.strip().split('\n')
print(lines)
for line in lines:
if 'exited' in lines:
continue
file = lines[0].split()[9][6:]
break
print file
return file
def main():
functions = [check_file]
for func in functions:
try:
func()
except Exception as e:
return False
if __name__ == '__main__':
main()
1. But if the file is not present we get index out of range error , do
we need to fix this or its expected ? or its ok.
machine-4# python c_4.py
isi_for_array 'ls -al /tmp2/2.txt'
machine-2 exited with status 1
machine-1 exited with status 1
machine-4 exited with status 1
machine-5 exited with status 1
machine-3 exited with status 1
['machine-2 exited with status 1', 'machine-1 exited with status 1',
'machine-4 exited with status 1', 'machine-5 exited with status 1',
'machine-3 exited with status 1']
ERROR:root:list index out of range
3. Any other tips to improve the program
