A tweak using Patola's code as a base, this full-width green matrix display has all the frills (and all the printable characters). You don't need the surrounding parens if you don't care about losing globbing capabilities. Z-shell (/bin/zsh) needs neither the parens nor the `set -o noglob` Screen shot (animated): http://desmond.imageshack.us/Himg32/scaled.php?server=32&filename=matrixh.gif&res=landing If it's too slow, try lowering the `sleep 0.05` or even replacing it with `true` (which is faster than `sleep 0`). I squashed it as narrow as I could to conserve space, though somebody could probably squeeze a char or two out. Enjoy!
Where filein is the source file, destination.com is the ssh server im copying the file to, -c arcfour,blowfish-cbc is selecting the fastest encryption engines, -C is for online compressions and decompression when it comes off the line - supposed to speed up tx in some cases, then the /tmp/fileout is how the file is saved... I talk more about it on my site, where there is more room to talk about this: http://www.kossboss.com/linuxtarpvncssh and http://www.kossboss.com/linux---transfer-1-file-with-ssh Show Sample Output
3143 is the latest revision with a file
I always forget this one and find all kinds of complex solutions on google. Also works great while piping data. ex. 'cat data | process-data | tr -d "\"" > processed-data-without-quotes'
This command telnet and and looks for a line starting with "SSH" - works for OpenSSH since the SSH banner is something like "SSH-2.0-OpenSSH_6.0p1 Debian-4+deb7u3". Then it triggers an action accordingly.
It can be packed as a script file to echo 0/1 indicating the SSH service availability:
if [[ "$(sleep 1 | telnet -c <host> <port> 2>&1 | grep '^SSH')" == SSH* ]]; then echo 1; else echo 0; fi;
Alternative uses:
Trigger an action when server is UP (using &&):
[[ "$(sleep 1 | telnet -c <host> <port> 2>&1 | grep '^SSH')" == SSH* ]] && <command when up>
Trigger an action when server is DOWN (using ||):
[[ "$(sleep 1 | telnet -c <host> <port> 2>&1 | grep '^SSH')" == SSH* ]] || <command when down>
You define your variable MYVAR with the desired search pattern: MYVAR= ...which can then be searched with the find command. This is useful if you in a script, where you want the arguments to be fed into the find command. The provided search is case insensitive (-iname) and will find all files and directories with the pattern MYVAR (not exact matches). This may go without saying, but if you want exact matches remove the \* and if you want case sensitive, use the -name argument.
also works in vim
