2 Execute multiple py files
2.1 Sequential execution
modified cdpath
#!/bin/bash
cd /public/home/data/test/
python3 test1.py
python3 test2.py
python3 test3.py
python3 test4.py
python3 test5.py
python3 test6.py
! If it is uploaded to the liunx server from windows, the shell script executes an error: /bin/bash^M: bad interpreter: No such file or directory
Reason : the file in the windows environment is in dos format, and the end of each line is marked with \r\n; The file under linux is in unix format, and the end of the line is marked with \n.
Check the file : 1. In the output of
cat -A test.sh, the end of the line is ^M, which is in dos format, and if the end of the line is just, it is in unix format. 2.vim test.sh, execute ":set ff", if the execution result is fileformat=dos, it will be in dos format, if the execution result is fileformat=unix, it will be in unix format
Solution:
1. sed -i "s/\r//" test.sh or sed -i "s/^M//" test.sh, directly replace the carriage return with an empty string.
2. vim test.sh, execute ": set ff=unix", set the file to unix format, save and exit.
2.2 Multi-process execution

./run.sh restart 2>&1 |tee -a mylog.log
