Check These Out

Display all shell functions set in the current shell environment
Uses the shell builtin `declare` with the '-f' flag to output only functions to grep out only the function names. You can use it as an alias or function like so: alias shfunctions="builtin declare -f | command grep --color=never -E '^[a-zA-Z_]+\ \(\)'" shfunctions () { builtin declare -f | command grep --color=never -E '^[a-zA-Z_]+\ \(\)'; }

Install pip with Proxy
Installs pip packages defining a proxy

dd with progress bar and remaining time displayed

The NMAP command you can use scan for the Conficker virus on your LAN
This was posted on reddit. replace 192.168.0.1-256 with the IP's you want to check.

Watch the progress of 'dd'
dcfldd is a forensic version of dd that shows a process indicator by default.

Get duration of an audio file in seconds.
This is an alternative to #9131. ffmpeg didn't work on my .au files, though it did on the .wav ones. Also useful if you don't have ffmpeg but do have sox. Handily, sox already reports in seconds (decimal).

list block devices
Shows all block devices in a tree with descruptions of what they are.

parse html/stdin with lynx
strips html from stdin

create ext4 filesystem with big count of inodes
XX is your device partition number like /dev/sdc1 . to see how many inodes your partition have type: $ df --inodes (or df -i) Default formatting with ext4 would create small inode count for the new partition if you need big count of inodes is the fstype news the correct one. in debian you can see which fstype exists as template in: $ vim /etc/mke2fs.conf if you format default ext for a partition size with 1TB you would get 1 Million inodes (not enough for backupStorages) but if you format with fstype news you would get hunderd of millions of inodes for the partition. you have tune $/etc/sysctl.conf also with following sysconfig parameters $ fs.file-max = XXX $ fs.nr_open = XXX where XXX is the count of max inodes for whole system

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