Hello There,

Kind of a newbie to shell scripting - need some help.

I need some help with shell script to check if the remote server is up & running (i guess i need to use ping) and to check if a particular file (say /home/<user-name>/somefile.txt) exists.

If any of the above 2 conditions are not met then i need to terminate/abort the script.

TIA for all your help,

regards,
sanju

With respect to ping you can find out the commandline to use doing 'man ping'. As far as the remote file check goes, determine what means of access you have, could be anything from SSH to HTTP to SNMP.
Being a "newbie" should not be used as an excuse for not reading stuff like BASH Programming - Introduction HOW-TO and http://www.tldp.org/LDP/Bash-Beginne...tml/index.html
(the http://www.tldp.org/LDP/abs/html/ prolly being a bit too steep). Look only for basic tests and exit codes.
Having read those now you can write some "pseudo code" people can comment on and before you know it you're no newbie no more.

before posting, i did browse the Linux Shell Scripting Tutorial posted on this forum - however, i did not find any reference to check files (or for that matter conditional checking) on remote servers.

The servers do have ssh access and i would like to do real-time checking just like we do on local server (if [-f <file-name>] ... ) rather than ftping the file back & forth.

something: if [-f ssh remote-server:/home/<user-name>/filename ] ... )

thanks.

ping -c 1 ipaddress && ssh user@host 'test -e /path/and/filename && echo exists'
