PostPosted: Thu 18 Apr 2013, 20:57    Post subject:  /usr/sbin/partview2  

Here is an attempt to speed up partview, which is launched by clicking the free space (frememapplet*) icon in the tray.

Main difference is the use of mount-FULL and umount-FULL PLUS option -o ro .
I think that it is not necessary to run ntfs-3g rw onto ntfs partitions, just to check for free space .
The downside is, that the drive icons don't get their dots all of the way. But that does not matters to me.

I bloated the code a little bit to use random coloration if /usr/*/X11/rgb.txt is available .

* Another attempt by technosaurus with xpm from 4.4 Alpha 1 times .

This partview still uses the old .gif format . I have tested recent partview and it uses some odd

case $ATAG in
[ "`dvd+rw-mediainfo /dev/${ATAG} 2>&1 | grep 'non-DVD'`" != "" ] && ASIZE=700000

lines to say that my 74MB sr3 USB MODEM iso9960 driver ROM Chip would have 4GB free of 4GB Laughing

[ My pup-430 partview had no header about the author. ]
It uses bash instead of ash for ash time function does not work on functions Crying or Very sad

# Karl Reimer Godt April 2013
# Rewrite for Puppy Linux /usr/sbin/partview shellscript .
# Main change : Using mount/umount-FULL -o ro to speed up reasonably,
# df -k|-m /mnt/data instead of df -k|-m | grep PATTERN ,
# support for running outside X , using random foreground colors.
# Minor changes : FREEK code rearranged and renamed FREEM + using -m option to probepart and df,
# dropped test for size-changes cos echo + diff + cp code is as heavy as ppmrough + ppmtogif,
# while + read instead of for loop,
# grep -vE 'unwanted|fs' instead of grep -E 'known|fs' .
# add homogeneous=\"true\" to hbox'es + rearrange text in hbox'es,
# check for gtkdialog2|3|4 and present rough xmessage instead if v2 .

# 04 put in LANG=C for dc command
# 03 added xmessage fallback, added random color
# 02 was wo random color, added check for gtkdialog2|3|4
# 01 was code cleanup, added ability to run in kernel console
# 00 was still -k , used jobs which does not work in 'not a tty'

Wish we knew how to burn to that fake iso part of usb modems, I once had a switchmode usb modem that had a puppylinux sized iso section for its windows drivers.
I would think it convenient to be able to use puppylinux as a booter that then would go online and pull the correct updated windows driver.
