bash - 找不到文件时sftp避免退出

Question

我有这个脚本:

filePattern='sor.log*'
filePattern2='sor.SOR.log*'
myLocation=/opt/tradertools/omer
clientLocation=/opt/tradertools/omer/sor/from
clientName=vmonitorlmpa
clientUser=root
clientPass=triltest

export SSHPASS=$clientPass

sshpass -e sftp -oStrictHostKeyChecking=no -oBatchMode=no -b - $clientUser@$clientName << !

    get $clientLocation/$filePattern2 $myLocation
    get $clientLocation/$filePattern $myLocation

   bye
!

但如果未找到 filepattern2，它将退出。如何避免使用两个 SFTP 连接？

Answer 1

引用sftp man page :

sftp will abort if any of the following commands fail: get, put, reget, reput, rename, ln, rm, mkdir, chdir, ls, lchdir, chmod, chown, chgrp, lpwd, df, symlink, and lmkdir.

Termination on error can be suppressed on a command by command basis by prefixing the command with a - character (for example, -rm /tmp/blah*).

所以使用:

-get $clientLocation/$filePattern2 $myLocation
