save.dat space usage help needed [Solved]

Post#1 by Ed_P » 04 Aug 2014, 04:25

When I use the command:

Code: Select all

du -h /mnt/live/memory/images/changes/home/guest*|grep  'M'
to find the larger users of my save.dat space in addtion to the

Code: Select all

11M	/mnt/live/memory/images/changes/home/guest/Backups/FireFox
11M	/mnt/live/memory/images/changes/home/guest/Backups
1.4M	/mnt/live/memory/images/changes/home/guest/.mozilla/firefox/c3pp43bg.default/extensions
16M	/mnt/live/memory/images/changes/home/guest/.mozilla/firefox/c3pp43bg.default
16M	/mnt/live/memory/images/changes/home/guest/.mozilla/firefox
16M	/mnt/live/memory/images/changes/home/guest/.mozilla
files I am also getting

Code: Select all

0	/mnt/live/memory/images/changes/home/guest/.cache/keyring-tKSMbQ
0	/mnt/live/memory/images/changes/home/guest/.cache/keyring-H9jOtM
0	/mnt/live/memory/images/changes/home/guest/.cache/keyring-SinMoc
0	/mnt/live/memory/images/changes/home/guest/.cache/keyring-MIzaGW
0	/mnt/live/memory/images/changes/home/guest/.cache/keyring-YUdMg8

files because they have an 'M' in the file name or path. How do I get just the 'M /mnt' ones?

I think I found a way.

Code: Select all

 du -h /mnt/live/memory/images/changes/home/guest*|grep  '[0-9]M'
And this works well for finding just the larger files/folders.

Code: Select all

 du -h /mnt/live/memory/images/changes/home/guest*|grep  '[0-9][0-9]M'

Code: Select all

du -haxt 10M /mnt/live/memory/images/changes/home/guest
I have a function in $HOME/.bashrc which also strips the containing parent directories.

Code: Select all

du_dummy() {
# Removes containing directories
# usage: [THRESHOLD DIR]|[DIR]
	[ "$2" ] && { opts="t $1"; dir="$2"; } || { unset opts; dir="$1"; }
	[ -z "$dir" ] && { dir="$PWD"; }
	du -hax$opts "$dir" 2>/dev/null | awk '
	BEGIN { printf "%6s %s\n", "Size","File or Directory/" }
	{
		dir=$2
		if ( prev_dir !~ dir ) {
			if (system("test -d \""dir"\"") == 0) { dir=dir"/" }
			printf "%6s %s\n", $1, dir
		}
		prev_dir=$2
	}'
}
alias du-='du_dummy'
(I know that I do not need to define an alias pointing to the function, but this gives me any easy way to see what's in my environment by just typing alias.)

An interesting command go2null. Thank you.

Interesting. I don't see this directory on my system.

$HOME is a more generic way of referring to your home directory. ~ is also used in some shells like bash and dash.

In the case of the Porteous guest user, it is
/home/guest

There you will find your. bashrc file.
/home/guest/.bashrc

You can copy and paste that into Geany's open file dialog.

Or you can enable showing hidden files in PCManFM or Geany Open File dialod.
(files that begin with a dot are hidden by default. )

Oh. Ok. I thought .bachrc was referring to a directory not a file. This is what I see.

Code: Select all

# Setup color scheme for list call <brokenman>
alias ll='/bin/ls --color=auto -lF'
alias la='/bin/ls --color=auto -axF'
alias ls='/bin/ls --color=auto -xF'

# Append any additional sh scripts found in /etc/profile.d/:
for y in /etc/profile.d/*.sh ; do [ -x $y ] && . $y; done
unset y

# Setup shell prompt for guest <wread and fanthom>

If you wish to add the function above, or any other function or alias, then you can directly add them to the $HOME/.bashrc file.
However, to make it easier to maintain your customizations, it's normal practice to use a separate $HOME/.bashrc_aliases or $HOME/.bashrc_personal file.

Here's a simple walk through for Porteous. (I'm using Porteous LXDE.)
(You can just copy and paste the entire code below into a terminal shell.)

Code: Select all

# add a hook so that your personal customizations will be 
#   automatically loaded whenever you launch a terminal.
echo '[ -e "$HOME/.bashrc_personal" ] && . "$HOME/.bashrc_personal"' >> $HOME/.bashrc

# create the personal file
cat > $HOME/1.bashrc_personal <<EOF
#!/bin/sh
# ^ not required, but allows for automatic syntax highlighting

du_dummy() {
# Removes containing directories
# usage: [THRESHOLD DIR]|[DIR]
	[ "$2" ] && { opts="t $1"; dir="$2"; } || { unset opts; dir="$1"; }
	[ -z "$dir" ] && { dir="$PWD"; }
	du -hax$opts "$dir" 2>/dev/null | awk '
	BEGIN { printf "%6s %s\n", "Size","File or Directory/" }
	{
		dir=$2
		if ( prev_dir !~ dir ) {
			if (system("test -d \""dir"\"") == 0) { dir=dir"/" }
			printf "%6s %s\n", $1, dir
		}
		prev_dir=$2
	}'
}
alias du-='du_dummy'
EOF

# source your personal file
. "$HOME/.bashrc_personal"

# see all your current aliases
alias

# now test your new function
du- 10M /

# And finally, open the file in a GUI editor
# for your enjoyment :-)
xdg-open "$HOME/.bashrc_personal"

Really!! Single lines I have done but never realized that multiple lines could be done.

The terminal window.

Code: Select all

guest@porteus:~$ # add a hook so that your personal customizations will be
guest@porteus:~$ #   automatically loaded whenever you launch a terminal.
guest@porteus:~$ echo '[ -e "$HOME/.bashrc_personal" ] && . "$HOME/.bashrc_personal"' >> $HOME/.bashrc

The revised .bashrc.

Code: Select all

# Setup color scheme for list call <brokenman>
alias ll='/bin/ls --color=auto -lF'
alias la='/bin/ls --color=auto -axF'
alias ls='/bin/ls --color=auto -xF'

PS2='> '
[ -e "$HOME/.bashrc_personal" ] && . "$HOME/.bashrc_personal"
And the new 1.bashrc_personal

Code: Select all

#!/bin/sh
# ^ not required, but allows for automatic syntax highlighting

du_dummy() {
# Removes containing directories
# usage: [THRESHOLD DIR]|[DIR]
   [ "" ] && { opts="t "; dir=""; } || { unset opts; dir=""; }
   [ -z "" ] && { dir="/home/guest"; }
   du -hax "" 2>/dev/null | awk '
   BEGIN { printf "%6s %s\n", "Size","File or Directory/" }
   {
      dir=
      if ( prev_dir !~ dir ) {
         if (system("test -d \""dir"\"") == 0) { dir=dir"/" }
         printf "%6s %s\n", , dir
      }
      prev_dir=
   }'
}
alias du-='du_dummy'
I'm unclear how this line "'[ -e "$HOME/.bashrc_personal" ] && . "$HOME/.bashrc_personal"' relates to the file named 1.bashrc_personal. Shouldn't the line have had "1.bashrc_personal" in it?
