问题
Have work on CentOS release 6.3 (Final) system. And try to ssh another machine using sshpass utility like
sshpass -p 'password' ssh user@host
But it give me error like
sshpass: Failed to run command: No such file or directory
So from error i think that sshpass may be not install so have try to install it by yum install sshpass and get following log
Loaded plugins: fastestmirror, refresh-packagekit, security
Loading mirror speeds from cached hostfile
* base: mirror.leapswitch.com
* epel: epel.mirror.net.in
* extras: mirror.leapswitch.com
* nux-libreoffice.org-rpms: mirror.li.nux.ro
* updates: mirror.leapswitch.com
Setting up Install Process
Package sshpass-1.05-1.el6.i686 already installed and latest version
Nothing to do
from above it seems sshpass is already installed.So why it not working?
回答1:
Check if your shell knows the locations of sshpass
which sshpass
If it doesnt give any output use find command to find the location of the executable:
find / -name sshpass
If you find the path, you can either use the full path of the executable:
/path/to/sshnpass
Or add the path to the PATH environmental variable, so that your shell can locate it:
export PATH=$PATH:/path/to/
Or the issue might be completely different. sshpass might not be able to find some other dependency. "ssh" client might not be installed. Or your syntax might be wrong:
