File manipulation place 0 before the number using sed
I'm new with sed, and i am really confused with slashes, backslashes, parentheses, I've tried reading some beginner's guide, but still trouble fixing this problem, do you have any tips where or what to read to learn more about sed? can you also help me with my problem?
Note: I was tasked to use sed on this.
Sample file:
I need to add 0 if the number in day is 1 only (ex. Oct 7 2019 to Oct 07 2019).
I've tried to sed, but the Oct 17 was changed to Oct 017
Thank you in advance

nwbpset
NWBPSET(1) nwbpset NWBPSET(1)NAME
nwbpset - Create a bindery property or set its value
SYNOPSIS
nwbpset [ -h ] [ -S server ] [ -U user name ] [ -P password | -n ] [ -C ]
DESCRIPTION
nwbpset Reads a property specification from the standard input and creates and sets the corresponding property. The format is determined by
the output of 'nwbpvalues -c'. nwbpset will hopefully become an important part of the bindery management suite of ncpfs, together with
'nwbpvalues -c'. See util/nwbpsecurity for an example.
As another example, look at the following command line:
nwbpvalues -t 1 -o supervisor -p user_defaults -c |
sed '2s/.*/ME/'|
sed '3s/.*/LOGIN_CONTROL/'|
nwbpset
With this command, the property user_defaults of the user object 'supervisor' is copied into the property login_control of the user object
'me'.
nwbpvalues -t 1 -o me -p login_control -c |
sed '9s/.*/ff/'|
nwbpset
This command disables the user object me.
Feel free to contribute other examples!
nwbpset looks up the file $HOME/.nwclient to find a file server, a user name and possibly a password. See nwclient(5) for more information.
Please note that the access permissions of $HOME/.nwclient MUST be 600 for security reasons.
OPTIONS -h
-h is used to print out a short help text.
-S server
server is the name of the server you want to use.
-U user
user is the user name to use for login.
-P password
password is the password to use for login. If neither -n nor -P are given, and the user has no open connection to the server, nwbpset
prompts for a password.
-n
-n should be given if no password is required for the login.
-C
By default, passwords are converted to uppercase before they are sent to the server, because most servers require this. You can turn off
this conversion by -C.
