Check These Out
can be used in script like :
echo $(wget -qO- http://utils.admin-linux.fr/ip.php)
Converts Unix epoch time to localtime. Useful for any logs that only display epoch time.
Mirror a remote directory using some tricks to maximize network speed.
lftp:: coolest file transfer tool ever
-u: username and password (pwd is merely a placeholder if you have ~/.ssh/id_rsa)
-e: execute internal lftp commands
set sftp:connect-program: use some specific command instead of plain ssh
ssh::
-a -x -T: disable useless things
-c arcfour: use the most efficient cipher specification
-o Compression=no: disable compression to save CPU
mirror: copy remote dir subtree to local dir
-v: be verbose (cool progress bar and speed meter, one for each file in parallel)
-c: continue interrupted file transfers if possible
--loop: repeat mirror until no differences found
--use-pget-n=3: transfer each file with 3 independent parallel TCP connections
-P 2: transfer 2 files in parallel (totalling 6 TCP connections)
sftp://remotehost:22: use sftp protocol on port 22 (you can give any other port if appropriate)
You can play with values for --use-pget-n and/or -P to achieve maximum speed depending on the particular network.
If the files are compressible removing "-o Compression=n" can be beneficial.
Better create an alias for the command.
MAC OSX doesn't come with an updatedb command by default, this will emulate the updatedb thats on a typical Linux OS.
Simply add it to your ~/.bash_profile
Same as the cool matrix style command ( http://www.commandlinefu.com/commands/view/3652/matrix-style ), except replacing the printed character with randomness. The command mentioned is much faster and thus more true to the matrix. However, mine can be optimized, but I wasted ... i mean spent enough time on it already
kaffeine could be replaced by any player able to read mms stream
You might want to secure your AWS operations requiring to use a MFA token. But then to use API or tools, you need to pass credentials generated with a MFA token.
This commands asks you for the MFA code and retrieves these credentials using AWS Cli. To print the exports, you can use:
`awk '{ print "export AWS_ACCESS_KEY_ID=\"" $1 "\"\n" "export AWS_SECRET_ACCESS_KEY=\"" $2 "\"\n" "export AWS_SESSION_TOKEN=\"" $3 "\"" }'`
You must adapt the command line to include:
* $MFA_IDis ARN of the virtual MFA or serial number of the physical one
* TTL for the credentials
