Executing shell scripts in the background

Execution mode:

Nohup sh export_data.sh 20150102 >20150102.log 2>&1 &[1] 29531

0, 1 and 2 respectively represent the following meanings:
0–stdin (Standard input)
1–stdout (Standard output)
2–stderr (standard error)

Nohup+ 's back & is to have the command execute in the background

>out.log is the output of information to the Out.log log

2>&1 is to convert standard error messages into standard output so that error messages can be exported to the Out.log log.
