I ran the foll. command:
The parted command (when I print the details) outputs something like below:
1 2048MB .......
what I want to bring in your notice that only 1 row came showing the complete size of the disk (detachable device) although I created 2 partitions with fdisk command.
The output of the below differs from above
It outputs 2 rows as I created 2 partitions. Why then parted command doesn't show it and shows the total size of the disk.
My other question :
When I put a fresh pendrive (without partitioning) it shows as one. (I mean it doesn't show that there are any partitions as I havent created any which is fine). Now when I create a partition say /dev/sdb1 (of /dev/sdb) then the output of fdisk shows sdb1. What about the remaining space. Now after creating a partition (sdb1), why then only sdb1 can be mounted and not the other part. Because earlier when there was no partition , it had mounted the complete disk.
Hello All, I am trying to list only directories in my current directory using the command "ls -d". But the output only contains the default directory "." and doesn't list the rest of the directories in the working directory. Can anyone explain why this is happening (2 Replies)

partx
PARTX(8) System Manager's Manual PARTX(8)NAME
partx - tell the Linux kernel about the presence and numbering of on-disk partitions
SYNOPSIS
partx [-a|-d|-s] [-t TYPE] [-n M:N] [-] disk
partx [-a|-d|-s] [-t TYPE] partition [disk]
DESCRIPTION
Given a device or disk-image, partx tries to parse the partition table and list its contents. It optionally adds or removes partitions.
The disk argument is optional when a partition argument is provided. To force scanning a partition as if it were a whole disk (for example
to list nested subpartitions), use the argument "-". For example:
partx --show - /dev/sda3
This will see sda3 as a whole-disk rather than a partition.
This is not an fdisk program -- adding and removing partitions does not change the disk, it just tells the kernel about the presence and
numbering of on-disk partitions.
OPTIONS -a, --add
Add the specified partitions, or read the disk and add all partitions.
-b, --bytes
Print the SIZE column in bytes rather than in human-readable format.
-d, --delete
Delete the specified partitions or all partitions.
-g, --noheadings
Do not print a header line.
-l, --list
List the partitions. Note that all numbers are in 512-byte sectors. This output format is DEPRECATED in favour of --show. Don't
use it in newly written scripts.
-o, --output list
Define the output columns to use for --show and --raw output. If no output arrangement is specified, then a default set is used.
Use --help to get list of all supported columns.
-r, --raw
Use the raw output format.
-s, --show
List the partitions. All numbers (except SIZE) are in 512-byte sectors. The output columns can be rearranged with the --output
option.
-t, --type type
Specify the partition table type -- aix, bsd, dos, gpt, mac, minix, sgi, solaris_x86, sun, ultrix or unixware.
-n, --nr M:N
Specify the range of partitions. For backward compatibility also the format <M-N> is supported. The range may contain negative
numbers, for example "--nr :-1" means the last partition, and "--nr -2:-1" means the last two partitions. Supported range specifi-
cations are:
<M> Specifies just one partition (e.g. --nr 3).
<M:> Specifies lower limit only (e.g. --nr 2:).
<:N> Specifies upper limit only (e.g. --nr :4).
<M:N> or <M-N> Specifies lower and upper limits (e.g. --nr 2:4).
EXAMPLES
partx --show /dev/sdb3
partx --show --nr 3 /dev/sdb
partx --show /dev/sdb3 /dev/sdb
All three commands list partition 3 of /dev/sdb.
partx --show - /dev/sdb3
Lists all subpartitions on /dev/sdb3 (the device is used as whole-disk).
partx -o START -g --nr 3 /dev/sdb
Prints the start sector of partition 5 on /dev/sda without header.
partx -o SECTORS,SIZE /dev/sda5 /dev/sda
Lists the length in sectors and human-readable size of partition 5 on /dev/sda.
partx --add --nr 3:5 /dev/sdd
Adds all available partitions from 3 to 5 (inclusive) on /dev/sdd.
partx -d --nr :-1 /dev/sdd
Removes the last partition on /dev/sdd.
