I am looking into creating my own terminal command from scratch. I researched online for some information on this subject was only able to view stuff related to OS X. I understand that they are both Unix based, are they both similar in creating these commands? Basically all I would like is for someone to point me towards the right direction to start or complete this task.
View 11 RepliesEvery time I boot up ubuntu I usually open 3 terminal windows and ssh into the same server. I would like to either click a shortcut, or run a single terminal command that will do the equivalent.
I came across the "gnome-terminal" command, but I was unable to get it to trigger an ssh command.
Ideally I would like to have a script that I pass in the number of windows I want to open and the server I would like to ssh into for each window.
Trying to COPY some of my DVDs, I've had tons of problems with the various applications such as K3B and Brasero (not putting them down though, just my experience). Recently I found the commands to use dvdbackup, and it worked perfectly. I can copy my DVDs easily and flawlessly. Really happy about that. Is there a command-line way of creating DVDs? I've got to say that using the terminal has been the most reliable and robust for me. Is there a way to create DVDs via the terminal? I'm running Ubuntu 8.1 on a Dell laptop.

View 4 Replies View RelatedI encountered a question in the Redhat Skills Assessment regarding useradd: Which of the following cannot be defined when you create a user account with useradd?
a* A password expiration date.
b* The user's primary group.
c* The user's default shell.
d* The user's NIS or LDAP group.
e* The user's home directory.
Which is the correct answer? I have my own thinking which will be explained later.
I would like to create the shell which would support the LS command in C++. And the way the command prompt can be changed.
View 7 Replies View RelatedI want to create a Live USB ..I have the ISO image in the hard disk
Where Sdb is my USB
The copy operation is okay...It says no of records in / out and gives the statistics
But when I boot the system , getting the error:
Boot :
In some cases , the USB itself is not recognized by BIOS at boot..
My BIOS supports boot from USB ..I have Boot order 1. CD/DVD 2. USB 3. HDD
Also what is the filesystem to be adopted for dd?
I usually format using FAT or FAT 32
1.mkfs.vfat /dev/sdb -I (or)
2.mkdosfs /dev/sdb (or)
3.mkdosfs -F 32 /dev/sdb
What is the correct way of partitioning USB drive? - FAT or FAT 32....Most Live USB creators (unetbootin/LiLi Live/Usb Creator) recognize only FAT32...
I dont want a Linux filesystem (ext2,ext3 or 4or reiserfs)for my USB as it is not portable across many systems as MS OSes do not read them..Also I had little success in booting a USB when I partitioned it using ext2..I read somewhere that ext2 will not reduce the life of the USB drive compared to other fs.
I'm trying to create a user john with default password 'abcdef'. I used the following command.
useradd john -p abcdef
I can't login with the password. in /etc/shadow file I can see the password in clear text format. how I can create a user along with password.
I recently used the newusers command to generate several user accounts from a text file. That process seemed to go well until I tried to su into one of the new accounts.
This behavior appears for all the accounts that were created from the text file and the newusers command. It seems that several configuration files that should have been autogenerated for these new users were never created. I was able to confirm this was the problem by copying .bashrc and .bash_profile from a user that was created with the "useradd" command into the /home/newaccount directory. After logging off and logging into the newaccount again, the issue is corrected.For the record, I just read this forum post and I'm looking for an alternative to this. If this is the most efficient way to accomplish my goal, then I'll try the route mentioned in the thread. I'm still open to alternatives.
I can do:mkdir messages and then: touch messages/hello.txt Is there a command that will do both - create the directory if it doesn't exist, and then the empty file? Something like: touch -p messages/hello.txt
View 1 Replies View RelatedI want to run a linux command with apache through web browser and that's is not working. and it's working properly when I execute this command through terminal, where is the problem?
NOTE: apache have the privileges to execute the command
If I execute
cal 2013
in terminal, it echoes the calendar for the year 2013. For the matter of fun, I'd like the terminal to echo
This year won't come.
How should I do this? I tried adding it as an alias to .bashrc, but I cannot create aliases with spaces.
EDIT:
The final solution:
echo "cal() { if [[ $@ > "2012" ]]; then command echo "This year won't come."; else command cal "$@"; fi; }" >> ~/.profile && source ~/.profile

Starting from what I would think is completely from scratch, maybe worse. A friend set up this computer on unix/linux when I expressed interest. Truthfully I don't have even the slightest clue where to start other than to offer my complete humility. If I could start with getting my dvd and cd functions to work that would be a good start.
