A really fun vim oneliner for auto documenting your option's parsing in your script.

# print the text embeded in the case that parse options from command line.

# the block is matched with the marker 'CommandParse' in comment, until 'esac'

extract_cmdl_options()

{

# use vim for parsing:

# 1st grep the case block and copy in register @p + unindent in the buffer of the file itself

# 2nd filter lines which start with --opt or +opt and keep comment on hte following lines until an empty line

# 3rd discard changes in the buffer and quit

vim -n -es -c 'g/# CommandParse/+2,/^\s\+esac/-1 d p | % d | put p | %

-c 'g/^\([-+]\+[^)]\+\))/,/^\(\s\+[^- \t#]\|^$\)/-1 p' \

-c 'q!' $0

}

Can easily be scripted in order to show permission "tree" from any folder. Can also be formated with

column -t

{ pushd .> /dev/null; cd /; for d in `echo $OLDPWD | sed -e 's/\// /g'`; do cd $d; echo -n "$d "; ls -ld .; done; popd >/dev/null ; } | column -t

[ "$1" == "--help" ] && { sed -n -e '/^# Usage:/,/^$/ s/^# \?//p' < $0; exit; }

With this one liner you can easily output a standard help message using the following convention:

Usage: is the start marker

Stop at the last #

By using vim, you can also filter content on stdout, using vim's extra power, like search pattern offset!

No more awk of course, sorry.

details :

-e ex mode

-s silent

-c 'ex command' : global + start and end pattern + offset print (p)

-cq : quit

middlehost allows ssh access from where you are but not securehost.

Use nice ssh piping to simulate scp through A => B => C

setting up the shell function if left as an exercise for the reader. ;-)

Agent forwarding should avoid password typing.
