General :: Exit Bash Script - Add - Del - Edit User From Certain File Using Different CASE Variables
Mar 6, 2010
I have made a simple bash script through which i can add, del, edit user from certain file using different CASE variables. like
case
1. adduser
2. del user
3. edit user
Now i want to add a exit CASE like
1. adduser
2. del user
3. edit user
4. exit
Now i want to make a script such a way that, if user input is 4 then only script quit. I used with exit function also but it didn't work. if user press ENTER or other keys then also it quit the program.
I am trying to get bash script using zentity to exit if the user presses the cancel or close buttons.The exit codes are working fine; they read 1 or 0 depending on the status but it always assumes 0. This is the portion of the script: PHP Code:
function settings(){ result=$(zenity --height=30 --width=300 --list --checklist --title='Selection'--column=Boxes --column=Selections --column="Options"
mkvmerge -o <filename without extension>_TV.mkv -S <filename> && mkvextract tracks <filename> 3:<filename without extension>.*** && perl /home/brian/Desktop/ass2srt.pl <filename without extension>.*** && rm <filename without extension>.***
Doing these commands for multiple command line file inputs is the goal. So I can just type ./script.sh *.mkv in my terminal.This is what I have so far, but it doesn't work whatsoever.
while learning to write bash scripts, i decided to write some script that, given an integer as input, will tell you the square root of that integer (provided the integer in question is a perfect square). i have already done on using primarily if statements and a while loop. i decided that using a case statement would be a lot simpler and i would be able to make the script more functional. here is what i have so far
[Code]....
i have tried all posible combos of using -ge or >= but i get pretty much the same thing. the idea is, for now, if the input is greater than or equal to 0 that it will echo test. can you do this sort of thing with case statements? or will it only work if i give it specific values like [1-9] (if this is the case then i dont think the case statement will work for what i want to do)
I tried to add my wife , and when I put in a password for her, this error comes up."Please set a valid user name consisting of a lower case letter followed by lower case letters and numbers." I did all that and I still can't set a password for her.
Is there any inbuilt functionality in Unix shell script so that i can able to convert lower case string input to an upper case? I dont want to use high level languages like java,python or perl for doing the job.
if I can create a bash script that once executer will edit or replace a line a in a file this line is the first one and its just one character that needs to be changed from a 1 to a 0.
How do I go about this? it is for a game called EVE Online, heres what my .sh look like atm
#!/bin/sh echo fixing prefs.ini #fix for prefs goes here echo starting eve eve
I have $db and $DATE set in my bash script, then I need to join them like this: mysqldump --user=usr --password=pss --databases $db | gzip > /backups/sqlNew/$db_$DATE.sql.gz;
Unfortunately, that doesn't work. How do I properly join those 2 variables into a filename?
I have a problem with a very big script I wrote in bash, and now I need to modulirize it in at least four smaller scripts. The problem is, that most of the variables I have will need to be shared by all scripts.
My question is: is there a way to declare global variables in bash? So that I can use and change them in any of the scripts and every change in the variable can be "seen" by the other scripts later.
I've created a script that put in dynamic variables the value HELLO 1, HELLO 2 HELLO 5. And I put the values of this variables in the file text.txt. Here's the script:
Code: for i in $(seq 1 5); do eval ${i}=$(cat << EOF "HELLO" $i EOF); done cat > text.txt << EOF $1 $2
I've been writing a bunch of bash scripts to make possible non-interactive, secure, cron-based SVN checkouts with CollabNet's SVN client and GNOME Keyring Daemon (aka GKD) and one of the scripts was designed to start GKD, harvest its output, essentially a couple of environment variables, and export those variables in shell of a user the script is run as. All upon user login by sourcing a bash script in ~/.bashrc.The problem is that those environment variables will not be exported, because the script is being run in a sub-shell that exits upon it completion and environment variables get unset for good.Well, the question is how can those variables be set permanently, meaning they're exported and kept untouched even across login-logout sessions?
I am using Linux some years, but since I built a LFS, I feel noobish again. Now with the help of BLFS I am setting up my environment and somewhere I incidentally read, that not every variable is inherited by a child Bash shell. As for the $PS1 and $PS2 variables I know, that they are not inherited by non-interactive Bash shells (and there is no reason why they should in my opinion). Well, as for my first thread I hope the title gives enough information on what I want to know. But anyways: Which environment variables are not inherited by Bash shells?
For example, if I'm in csh, I can use `setenv VARNAME varVALUE` while I can use export in Bash. Given that the environmental variables are created, can BASH read env vars from csh and vice versa?
I have a user that has been used for long time now that runs o C Shell... now there is a need to change it to Bash Shell? Can I cause a problem changing his shell from C to bash? I mean apps or variables?
I have been give a task of replicating one of our production systems to create a test system. I have been restricted to use c shell to set up its environment variables. I am new to this my questions is how do i set environment variables for a particular user on c shell e.g ORACLE_HOME and ORACLE_SID permanently for a particualar user i know in bash you edit the .bash_profile file. What do i do for c shell?
So I need to become the root user in order to edit a grub file in a seperate partition, so I can get back into this partition. How can I become and stay as root user in the desktop environment? (I know you shouldn't do this, but I need it.)
I was looking at some Vim plugins, and I installed one called Abolish. The page from where I got it [URL] only says:
install details Extract in ~/.vim or ~vimfiles
So I extracted it in ~/.vim. Now, the issue is that, if I edit a file as root, I am able to use the commands; however, when I edit a file as a normal user, these commands won't work. So... could this be a permissions issue? Or should I copy the plugin in some other directory, maybe?
I am new to shell script and need to edit an xml form script. The XML file is something like code...
If the user selects element1, the script should modify only element1 values and not element2 values. I need it to be done from bash script. I can't use python or perl for the same. Please provide me a way to do so.
the following works and BASH doesn't complain, but VIM highlights the closing square bracket is if it sees a syntax error. Is there a better way to express regex in a case statement or is this an issue with VIM?
