I'm using ubuntu and apache2. Long story short, I'm password protecting a website. But the username and password will change everyday. So I've added entire month of password in /etc/apache2/.htpasswd file and I am going to run cronjob at everyday midnight to run a bash file and delete the password line for that day. My bashfile looks like this
#!/bin/bash</font>
> cat /etc/apache2/.htpasswd
> sudo sed '1d' /etc/apache2/.htpasswd
when I run the script, it shows this
./deleteline.sh: line2 /etc/apache2/.htpasswd: Permission denied
i changed permission for bash shell as well and it works well with other files.
So I would really appreciate it if you can tell me how I get rid of the permission error problem.

We have a partial LDAP integration on our RHEL servers. I'm trying to create a setup script to run on new servers. The first thing I need my script to do is log into an LDAP user account so that it's home directory gets created. If I put it in a script like so (and run as root):
#!/bin/bash
su - LDAPaccount
It fails saying the user doesn't exist.
If I just run the su - LDAPacccount command, then it creates the users home directory and switches me to that user. Anyone know why running the su command in a bash script fails and how I can get around this?
For anyone who finds this. My solution was to fully qualify everything:
#!/bin/bash
/bin/su - LDAPaccount -c "/usr/bin/ls"
When I run that, it works fine.
I'm currently using Sikuli to upload a PDF file to a website server. This seems inefficient. Ideally I would like to run a shell script and get it to upload this file on a certain day/time (i.e Sunday at 5AM) without the use of Sikuli.
I'm currently running Mac OS Yosemite 10.10.1 and the FileZilla FTP Client.
Any help is greatly appreciated, thank you!
Create a bash file like this (replace all [variables] with actual values):
#!/bin/sh
cd [source directory]
ftp -n [destination host]<<END
user [user] [password]
put [source file]
quit
END
Name it something like upload_pdf_to_server.sh
Make sure it has right permission to be executed:
chmod +x upload_pdf_to_server.sh
Set a cron job based on your need to execute the file periodically using command crontab -e
0 5 * * * /path/to/script/upload_pdf_to_server.sh >/dev/null 2>&1
(This one will execute the bash file every day at 5AM)

Hi, my name is Evan, newbie on UNIX :)
i want to ask about scripting on unix. here is the case :
i have 4 unix server (with freeBSD OS), let call them "Gorrila's"
And one gateway server (also, with unix FreeBSD OS), Let call this one "Monkey's"
if i want access and login to Gorillas server, i have to using putty to access Monkey and then, from monkey doing ssh connection to enter Gorillas server.
The case is, my boss asking to me, to get an apache error log, everday, in fourth of gorrila's server.
All this time, i am doing manually. putty to monkeys - ssh to gorrilas - copy error log into monkey server using scp command and then, get error log with winscp from monkeys server.
the problem is :
how to make script with this case ?
how to rename automatically the error_log because, error log name in every server has a same name. which is "01_error.log". i had to rename it manually so they can't replace each other.
i hope, somebody can help me with this.
All, Thank you for your help and time. and sorry for the bad english language. :)
The easiest way to accomplish this would be to setup an automated job on Gorilla4.
Your first problem, is that you'll need to setup password-less SSH access between Gorilla4 and Monkey so you don't need a person to physically type in the password.
While you can do this with the 'root' user I would STRONGLY recommend against it.
Instead create a maintenance user on BOTH hosts:
$ useradd -m maintuser
Then switch to the new user and create SSH key on Gorilla4:
$ ssh-keygen -t rsa -b 2048
Accept the defaults when prompted. Then copy the id_rsa.pub file to the ~/.ssh directory of the maintuser on Monkey.
Now, when you are the "maintuser" on Gorilla4, you can SSH to Monkey without a password.
Then you can create a script called "copy_log.sh":
#!/bin/bash
# copy_log.sh
log_path="/path/to/logdir"
log_name="01_error.log"
target_host="monkey"
echo "copying ${log_name} to ${target_host}..."
# note: $(hostname) below will add "Gorilla4" to the name of the file
scp ${log_path}/${log_name} maintuser#${target_host}:/path/to/dest/$(hostname)_${log_name} || {
echo "Failed to scp file"
exit 2
}
echo "completed successfully"
Make it executable:
$ chmod +x copy_log.sh
Add it to the maintuser's crontab on Gorilla4 to run at whatever time you would nomrally do it yourself, say 8am everyday:
00 08 * * * /path/to/copy_log.sh >> /some/log/dir/copy_log.out 2>&1
Hope this helps; if nothing else, it will give you plenty to Google :)
I am trying to write a script to automatically upload files to a sftp server. My problem is authentication.
I know it is not possible to store a password in a bash script for sftp.
I can't use keys because the admin of the server won't allow me.
I don't want to use any extras (sshpass/expect) because I can't
guarantee they will be on the machine I'm using (the script are wanted so that the processes are not tied down to a particular machine).
Manual entry of the password is not a problem I just need to get the script to wait for the user to put the password in. At the minute when I run the script it opens terminal, prompts for the password, but when this is entered nothing else happens. If I enter the lines of code manual after it uploads everything correctly.
#!bin/bash/
cd /remote_directory
lcd /local_directory
put some_file.txt
After months of looking for an answer I have finally found the solution. It was in a comment on an answer in some other thread I can't even remember. Hope this can help others out there.
Your bash script should look like this and will connect to the sftp server, prompt the user for the password, and then execute the remaining commands.
#!/bin/bash
sftp user#server <<!
cd /the/remote/directory
lcd /your/local/directory
put/get some.file
!
I've tried my best to find out a solution with the many script questions on Stack Overflow and the internet, but I can't seem to find the solution I need.
What I want to do is create a more automated and less clicking solution to remove all the Mobile cached user accounts on a system. I've been logging in and manually going to user accounts and removing the users one at a time by clicking the "-" button, then clicking "Delete Immediately" for the user data. This works, but is time consuming and I have better things to do with my time. So I knew there had to be a way to do this with a script.
I ran across this code:
for cuser in `dscl . -list /Users AuthenticationAuthority | grep LocalCachedUser | awk '{print $1}' | tr '/n' ' '`; do
dscl . -delete /Users/$cuser
done
If I run this in terminal I get permission errors. So I figured I need to run it with sudo. So I started looking into creating AppleScripts to run the script, but I can't seem to find the right way to do it.
Any ideas? By the way, I'm new to scripting on the Mac, so please comment your code so I know whats happening, and so I don't just run some script code without know what it'll do. :)
Thanks
To perform a shell script with sudo or administrator privileges append with administrator privileges to the end of your do shell script line. For example:
do shell script "/path/to/script/file.sh" user name "adminusershortname" password "password" with administrator privileges
You can find more on Apple's technote dealing with do shell script
That said, saving this as a shell script and running the shell script using sudo would work just as well.
#! /bin/sh
for cuser in `/usr/bin/dscl . -list /Users AuthenticationAuthority | grep LocalCachedUser | awk '{print $1}' | tr '/n' ' '`; do
/usr/bin/dscl . -delete /Users/$cuser
done
Save it as say removeUser.sh, use chmod to set it as executable (chmod 755) and then run it (sudo ./removeUser.sh)
You can do this by editing your system's sudoers file. This will allow the account you use to run this script (via cron, etc.) the ability to run sudo without a password.
To edit the sudoers file you use visudo, but it must be run with admin permission. Try:
$ sudo visudo
Add a line like the following to the end of the file, replacing user_name with the user who will run your script. Note, use tabs between each field.
user_name ALL=(ALL) NOPASSWD:ALL
Now user_name should be able to type sudo and will not be prompted for a password.
Also note that visudo is a text editor that mirrors the vi editor and uses the same commands as vi.
I don't have a mac handy so I can't verify if this would work.
Try running
su -
Then running your script. If that works, try
crontab -e
and adding an entry to run that script of yours.
Are you familiar with crontab? well if not google it if need be.
But basically to run it every day at midnight you'd have something like
0 * * * * /path/to/script
