Question

Can someone tell me why my variable will only return all .txt files or all .log files but not both together. I thought I understood this, as I have used similar cases before with an if statement and qn endswith method of text or log extension. But, with getting files from a server it’s only allowing me to get one or another. I’m sure it’s the syntax … I have very little experience with Python. Any help is appreciated:

This line works fine or a variation with .txt:

  apattern = '"*.log"'

However, this line searches for .log files only:

  apattern = (('"*.txt" ') or ('"*.log" '))

Code:

 import paramiko
 import sys
 import os





 ssh = paramiko.SSHClient()
 ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
 ssh.connect('10.5.48.72', username='root', password='*****')


 apath = '/'
 apattern =  '"*.{txt,log}"' #(('"*.txt" ') and ('"*.log" '))
 rawcommand = 'find {path} -name {pattern}'
 command = rawcommand.format(path=apath, pattern=apattern)
 stdin, stdout, stderr = ssh.exec_command(command)
 filelist = stdout.read().splitlines()


 ftp = ssh.open_sftp()
 for afile in filelist:
    (head, filename) = os.path.split(afile)
    print(filename)
    ftp.get(afile, 'c:\\ANewOne\\' + filename)  #'./'+filename)
 ftp.close()
 ssh.close()

Answer 1

apattern = '"*.{txt,log}"'

Should combine the extensions using unix-style shell expansion.

Another variant for the find utility would be

apattern = '"*.txt" -o -name "*.log"'

Maybe you can try this, too. This will construct the command

find {path} -name "*.txt" -o -name "*.log"
