Kev:
Try the command line tool expand.
expand -t 4 input >output
And for those systems that don’t use the GNU Core Utilities, you have a decent chance of expand being installed since it is standardized by The Open Group’s Single Unix Specification. See Issue 6, which is from 2001, though some updates were applied, hence the year of publication being 2004: expand

Since quite a few commands that you regularly see mentioned on the web have been removed from OpenSuSE net-tools, I’ve created a few bash aliases in /etc/bash.bashrc.local below.
Note the original commands are not good have been deprecated for years on various distros and therefore removed:
# stuff removed from net-tools # see https://features.opensuse.org/317197 and https://build.opensuse.org/package/view_file/network:utilities/net-tools/net-tools.changes ## Because of changes on Thu Apr 10 12:33:41 UTC 2014 alias "arp=echo 'use \"ip neigh\" or \"ip -r neight\"' && ip neigh" alias "ifconfig=echo 'use \"ip a\"' && ip a" alias "netstat= echo 'use \"ss\" or \"ss -r\"' && ss" alias "route=echo 'use \"ip r\"' && ip r" ## Because of changes on Sun Mar 29 00:41:21 UTC 2015 alias "ipmaddr=echo 'use \"ip maddr\"' && ip maddr" alias "iptunnel=echo 'use \"ip tunnel\"' && ip tunnel"
Some bits of the net-tools change-log:
------------------------------------------------------------------- Sun Mar 29 00:41:21 UTC 2015 - jengelh@inai.de - ipmaddr and iptunnel are obsolete too, move them to subpackage. (Superseded by `ip maddr` and `ip tunnel`) - remove redundant %clean section ------------------------------------------------------------------- Thu Apr 10 12:33:41 UTC 2014 - mmarek@suse.cz - Move arp, ifconfig, netstat and route to a -deprecated subpackage (fate#317196, fate#317197) - Drop the rarp tool, which has been broken since kernel 2.3
Note that the -lntu parameter seems to be the same for both ss and netstat: [WayBack] Get a list of Open Ports in Linux – Super User

I needed to find the symlinks in /etc pointing to directories and know both the name and place they point to.

Since ESXi is based on busybox, it is using ash a variation of sh (the classic bourne shell) called Almquist shell and most nxes use some form of bash a lot of things won’t work.
For instance, doesn’t support sh –version.
Luckily there are uname -mrs and (more elaborate) vmware -vl to get the version.
Note there is support busybox aliases so alias dir=”ls -laF” works, and you can define aliases for the version information too.

Many sites giving your public IP address return a web page with a bloat of html. From the command-line, you are usually only interested in the IP-address itself. Few services return exactly that.
Below are command-line examples to provide the public IP address mostly from a *nix perspective. Usually you can get similar commands to work with Windows binaries for wget and Windows binaries for curl.
In the end, I’ve opted for commands in this format, as I think akamai will last longer than the other sites (but does not include an end-of-line in the http result hence the echo on Mac/*nix):
I’ve not tried aria2 yet, but might provide commands for that in the future.
These are the Linux permutations for akamai:
curl whatismyip.akamai.com && echo curl ipv4.whatismyip.akamai.com && echo curl ipv6.whatismyip.akamai.com && echo curl ipv4.whatismyip.akamai.com && echo && curl ipv6.whatismyip.akamai.com && echoThe last two are convenient when you have both IPv4 and IPv6 configured on “the outside”.
You can replace curl with wget -q -O – (which outputs to stdout) for each command. You can even ommit the http:// (as that is the default protocol for both curl and wget).
