Hi all,
First of all I dont even know the ABC of scripting ..
But now I want a Script to see the mount points of the file systems
Can any body help plsssssssss :o (1 Reply)
so I've made a shell script that downloads 6 files in succession from a given url, then deletes them. Now I want to time the script, and the average time it uses by running it ~100 times. My problem is tho, how do I store the time it takes for each run through of the script? I know time writes to... (3 Replies)

Hi All,
I need the modification for the below mentioned code (found in one more post https://www.unix.com/shell-programming-scripting/27161-script-generate-average-values.html) to find the average values for all the columns(but for a specific rows) and print the averages side by side.

Hi Everyone,
Just in need of your help again, I have managed to get a script to check the linux disk usage stuff. But wanted to tweak it little more to get the desired output.
Requirement:
Now its querying only one mount point, As its not saving in array instead calling it as variables. So... (1 Reply)
Im looking for a way to average the values in field 14 (when field 2 is equal to 2016) and fields 3 and 4 (when field 2 is equal to 2017).
Any help is appreciated.

measurefs.reiser4
measurefs.reiser4(8) reiser4progs manual measurefs.reiser4(8)NAME
measurefs.reiser4 - the program for measuring reiser4 filesystem parameters (fragmentation, node packing, etc.).
SYNOPSIS
measurefs.reiser4 [ options ] FILE
DESCRIPTION
measurefs.reiser4 is reiser4 filesystem measure program. You can estimate reiser4 filesystem fragmentation, packingm etc. structures by
using it.
COMMON OPTIONS -V, --version
prints program version.
-?, -h, --help
prints program help.
-y, --yes
assumes an answer 'yes' to all questions.
-f, --force
forces measurefs to use whole disk, not block device or mounted partition.
-c, --cache N
sets tree cache node number to passed value. This affects very much behavior of libreiser4. It affects speed, tree allocation, etc.
MEASUREMENT OPTIONS -S, --tree-stat
shows different tree statistics (node packing, internal nodes, leaves, etc)
-T, --tree-frag
measures total tree fragmentation. The result is fragmentation factor - value from 0.00000 (minimal fragmentation) to 1.00000 (maxi-
mal one). Most probably, this factor may affect sequential read performance.
-D, --data-frag
measures average files fragmentation. This means, that fragmentation of each file in filesystem will be measured separately and
results will be averaged. The result is fragmentation factor - value from 0.00000 (minimal fragmentation) to 1.00000 (maximal one).
Note, that for the fresh filesystem (created not very long time ago) and even fully filled by data, this value will be pretty small.
-F, --file-frag FILE
measures fragmentation of the specified file. The result is fragmentation factor - value from 0.00000 (minimal fragmentation) to
1.00000 (maximal one). Note, that fragmentation of a small file (depends of used tail policy), which consists of tail items, is not
very reliable value. That is because, they is always afoot due to balancing.
Examples:
measurefs.reiser4 -F /usr/bin /dev/hda2
measurefs.reiser4 -F /bin/bash /dev/hda2
-E, --show-file
show file fragmentation for each file if --data-frag is specified.
PLUGIN OPTIONS -p, --print-profile
prints the plugin profile. This is the set of default plugins used for all parts of a filesystem -- format, nodes, files, directo-
ries, hashes, etc. If --override is specified, then prints modified plugins.
-l, --print-plugins
prints all plugins libreiser4 know about.
-o, --override TYPE=PLUGIN, ...
overrides the default plugin of the type "TYPE" by the plugin "PLUGIN" in the plugin profile.
Examples:
measurefs.reiser4 -o nodeptr=nodeptr41,hash=rupasov_hash /dev/hda2
