Get only headers from a website with curl even if it doesn't support HEAD

Some sites running on basic web servers don't support the HEAD request, so using "curl -I" on them doesn't work. This will automatically try "curl -I" at first and if that fails with a 4xx or 5xx status code, it falls back to "curl -i" and prints only the headers from that.
This is sample output - yours may be different.

Get primary IP of the local machine

Plenty of commands out there for finding external IP, but sometimes getting the [internal] IP bound to the NIC handling Internet traffic is useful. Probably not production worthy, but a useful quick kludge. Assumes IPv4 and no fancy routing. Show Sample Output

Automatically update all the installed python packages

There are two different ways that I would have done this. With the command posted or if you prefer xargs: pip freeze --local | awk -F "=" '{$1}' | xargs pip install -U # But this is a moot point considering the above replaces xargs

Produce a pseudo random password with given length in base 64

Of course you will have to install Digest::SHA and perl before this will work :) Maximum length is 43 for SHA256. If you need more, use SHA512 or the hexadecimal form: sha256_hex()

Copy files and directories from a remote machine to the local machine

This command will copy files and directories from a remote machine to the local one. Ensure you are in the local directory you want to populate with the remote files before running the command. To copy a directory and it's contents, you could: $ ssh user@host "(cd /path/to/a/directory ; tar cvf - ./targetdir)" | tar xvf - This is especially useful on *nix'es that don't have 'scp' installed by default.

Sort the size usage of a directory tree by gigabytes, kilobytes, megabytes, then bytes.

Probably only works with GNU du and modern perls.

Print Memory Utilization Percentage For a specific process and it's children

Change the name of the process and what is echoed to suit your needs. The brackets around the h in the grep statement cause grep to skip over "grep httpd", it is the equivalent of grep -v grep although more elegant.

get all bookmarks from all profiles from firefox

for i in $(ls /home/marco/.mozilla/firefox/*\.*/places.sqlite); do sqlite3 $i "SELECT strftime('%d.%m.%Y %H:%M:%S', dateAdded/1000000, 'unixepoch', 'localtime'),url FROM moz_places, moz_bookmarks WHERE moz_places.id = moz_bookmarks.fk ORDER BY dateAdded;"; done

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
