Hi Friends,
I have a requirement to parse a properties file having a key=value pairs.
i need to count the number of key value pairs in the properties file and iterate through each key-value pair. I have written the script to read the number of lines from the property file, but cannot iterate through the count since the total number of lines is in string. Can you please help me in completing the below script.
Kindly find the script below
sample properties file
Desired output from shell script:
It should read the number of line which is 4. And then iterate 4 times using for loop and then printing the name and the value for each key value.
-- please use code tags

Hi,
I have noticed that rm -if will perform completely different to rm -fi. Whats the pattern of how I put my options to the script in relation to how it will act.
i.e
rm -fi treat the remove as interative but
rm -if treats it as forced

Hi ,
I do have a line in my code as follows:
if ] ; then

else

fi
What does the -z does ? Similarly there is -s in some other part of the code. I guess there are many options like this.. Can anybody please tell what all options are available and what do they mean ? (2 Replies)

hwdb
HWDB(7) hwdb HWDB(7)NAME
hwdb - Hardware Database
DESCRIPTION
The hardware database is a key-value store for associating modalias-like keys to udev-property-like values. It is used primarily by udev to
add the relevant properties to matching devices, but it can also be queried directly.
HARDWARE DATABASE FILES
The hwdb files are read from the files located in the system hwdb directory /lib/udev/hwdb.d and the local administration directory
/etc/udev/hwdb.d. All hwdb files are collectively sorted and processed in lexical order, regardless of the directories in which they live.
However, files with identical filenames replace each other. Files in /etc have the highest priority and take precedence over files with the
same name in /lib. This can be used to override a system-supplied hwdb file with a local file if needed; a symlink in /etc with the same
name as a hwdb file in /lib, pointing to /dev/null, disables that hwdb file entirely. hwdb files must have the extension .hwdb; other
extensions are ignored.
Each hwdb file contains data records consisting of matches and associated key-value pairs. Every record in the hwdb starts with one or more
match strings, specifying a shell glob to compare the lookup string against. Multiple match lines are specified in consecutive lines. Every
match line is compared individually, and they are combined by OR. Every match line must start at the first character of the line.
The match lines are followed by one or more key-value pair lines, which are recognized by a leading space character. The key name and value
are separated by "=". An empty line signifies the end of a record. Lines beginning with "#" are ignored.
In case multiple records match a given lookup string, the key-value pairs from all records are combined. If a key is specified multiple
times, the value from the record with the highest priority is used (each key can have only a single value). The priority is higher when the
record is in a file that sorts later lexicographically, and in case of records in the same file, later records have higher priority.
The content of all hwdb files is read by systemd-hwdb(8) and compiled to a binary database located at /etc/udev/hwdb.bin, or alternatively
/lib/udev/hwdb.bin if you want ship the compiled database in an immutable image. During runtime, only the binary database is used.
EXAMPLES
Example 1. General syntax of hwdb files
# /lib/udev/hwdb.d/example.hwdb
# Comments can be placed before any records. This is a good spot
# to describe what that file is used for, what kind of properties
# it defines, and the ordering convention.
# A record with three matches and one property
mouse:*:name:*Trackball*:
mouse:*:name:*trackball*:
mouse:*:name:*TrackBall*:
ID_INPUT_TRACKBALL=1
# A record with a single match and five properties
mouse:usb:v046dp4041:name:Logitech MX Master:
MOUSE_DPI=1000@166
MOUSE_WHEEL_CLICK_ANGLE=15
MOUSE_WHEEL_CLICK_ANGLE_HORIZONTAL=26
MOUSE_WHEEL_CLICK_COUNT=24
MOUSE_WHEEL_CLICK_COUNT_HORIZONTAL=14
Example 2. Overriding of properties
# /lib/udev/hwdb.d/60-keyboard.hwdb
evdev:atkbd:dmi:bvn*:bvr*:bd*:svnAcer*:pn*
KEYBOARD_KEY_a1=help
KEYBOARD_KEY_a2=setup
KEYBOARD_KEY_a3=battery
evdev:atkbd:dmi:bvn*:bvr*:bd*:svnAcer*:pn123*
KEYBOARD_KEY_a2=wlan
# /etc/udev/hwdb.d/70-keyboard.hwdb
# disable wlan key on all at keyboards
evdev:atkbd:*
KEYBOARD_KEY_a2=reserved
If the hwdb consists of those two files, a keyboard with the lookup string "evdev:atkbd:dmi:bvnAcer:bdXXXXX:bd08/05/2010:svnAcer:pn123"
will match all three records, and end up with the following properties:
KEYBOARD_KEY_a1=help
KEYBOARD_KEY_a2=reserved
KEYBOARD_KEY_a3=battery
