Speed Up WAN File Transfer With Compression

If you have servers on Wide Area Network (WAN), you may experience very long transfer rates due to limited bandwidth and latency. To speed up you transfers you need to compress the data so you will have less to transfer. So the solution is to use a compression tools like gzip or bzip or compress before and after the data transfer. Using ssh "-C" option is not compatible with every ssh version (ssh2 for instance).

avoid ssh hangs using jobs

Execute commands serially on a list of hosts. Each ssh connection is made in the background so that if, after five seconds, it hasn't closed, it will be killed and the script will go on to the next system. Maybe there's an easier way to set a timeout in the ssh options...

ls not pattern

Negative shell globs already come with bash. Make sure to turn on extended pattern matching with 'shopt -e extglob'.

ls not pattern

Hides some entries from listing.

List symbols from a dynamic library (.so file)

You can get what functions at which addresses are inside a dynamic link library by this tool.

Hex math with bc

To do hex to binary: echo 'ibase=16; obase=2; 16*16' | bc # prints: 111100100 To do 16*16 from decimal to hex: echo 'ibase=10; obase=16; 16*16' | bc # prints: 100 You get the idea... Alternatively, run bc in interactive mode (see man page)

Display the output of a command from the first line until the first instance of a regular expression.

Slightly simpler version of previous sed command that does the same thing. In this case, the output will stop at the command, and the entire command will be terminated as well, instead of proceeding through the whole file.

Count items in JSON array

Pipe any JSON to jq, then count with the appropiate expression and use the | length on the array

Convert DOS newlines (CR/LF) to Unix format

Find out which debian package a command (executable) belongs to on debian-based distros

This revision to my command (command #8851) was called for when it failed to find the parent package of 'rlogin', which is really a deep symbolic link to /usr/bin/ssh. This revision fixes this newfound issue, while ensuring fixes of other older issues work too.

Filter the output of a file continously using tail and grep

The OPs solution will work, however on some systems (bsd), grep will not filter the data, unless the --line-buffered option is enabled.

makes screen your default shell without breaking SCP or SFTP

I changed my shell to screen by editing .bashrc, this stopped scp from connecting. Adding two tests before screen fixed them problem.
