I have a bash script to download data from a website. For this I need to pass the username and password using a java client for the website. My password has a special character that is causing problems. I have tried the usual solutions but none are working.
#!/bin/sh
#$ -cwd
MYPASSWORD='password&123'
java -jar client.jar -p username $MYPASSWORD file.gz
Tried using \ either directly in the command or using the variable. But that didnt work. Login failed!
MYPASSWORD=password\&123
java -jar client.jar -p username $MYPASSWORD file.gz
Tried "" or ''. Login failure.
MYPASSWORD='password&123'
java -jar client.jar -p username "\"$MYPASSWORD\"" file.gz
Also tried it, no luck.
MYPASSWORD='password'"&"'123'
Any suggestions would be most helpful. Resetting the password on this website also seems problematic.
Just quote the parameter.
mypassword='password&123'
java -jar client.jar -p username "$mypassword" file.gz
The quotes are only there to keep the shell from performing any further processing of the value of mypassword after the parameter is expanded. You don't actually pass quotes to your program.

I had to automate my postgre database backup. As instructed by my software vendor I am trying to use pg_dump.exe (see below) file to take a backup but that prompts me for password.
.\pg_dump.exe -h localhost -p 4432 -U postgres -v -b -F t -f "C:\Backup\Backup.tar" Repo
So googled and found that as per "https://www.postgresql.org/docs/9.6/libpq-pgpass.html" I can create a pgpass.conf file within 'C:\Users\User1\AppData\Roaming\postgresql\pgpass.conf" which I did.
Then I tried to pass data of pgpass.conf file to env variable before executing my pg_dump command. But it is not working. Still I am getting prompt to enter password. This is the content of pgpass.conf file: *:*:*:postgres:password
Below is the code I am trying in PowerShell,
$Env:PGPASSFILE="C:\Users\User1\AppData\Roaming\postgresql\pgpass.conf"
cd "C:\Program Files\Qlik\Sense\Repository\PostgreSQL\9.6\bin"
.\pg_dump.exe -h localhost -p 4432 -U postgres -v -b -F t -f "C:\Backup\Backup.tar" Repo
Why am I still being asked for password?
When I type following code $Env:AppData I get following response "C:\Users\User1\AppData\Roaming"
Everywhere there are guidance on how to use it in UNIX or command prompt but not in powershell. Any help is appreciated. Also if you could direct me how to secure this password file then it will be great.
With password prompt I cannot automate it with windows task scheduler.
I suspect you have a suitable solution, however, as a quick (and not secure) workaround via the command prompt, you can use the variable PGPASSWORD to hold the password then run the backup script.
A sample might be something like:
SET PGPASSWORD=password
cd "C:\Program Files\Qlik\Sense\Repository\PostgreSQL\9.6\bin" pg_dump.exe -h localhost -p 4432 -U postgres -b -F t -f "d:\qs_backup\QSR_backup.tar" QSR

I have yet to get the damned thing to work yet, but I did find this:
-w
--no-password Never issue a password prompt. If the server requires password authentication and a password is not available by other means
such as a .pgpass file, the connection attempt will fail. This option
can be useful in batch jobs and scripts where no user is present to
enter a password.
I don't see a -w parameter in your call to pg_dump
I used pg_hba file to allow connection "trust" this is riskier method but I had to get things done ASAP. Thank you for your time and effort
I have a shell script which is trying to login into a box with password having special character.
sshpass -p"\"$Passw\"" ssh -tt -o StrictHostKeyChecking=no root#"${Hostname}"
I am passing Hostname and Password parameter from Jenkins. Password conatins $ characater for example n$1sachin . But I am not able to login. Can anyone please help?
I tried different option but its not working for me.
I have encounter similar problem, finally using \ to escape special char in password is work for me, such as:
from xxx)xxx#?xxx to xxx\)xxx\#\?xxx
full command like this:
sshpass -p xxx\)xxx\#\?xxx rsync -avzh ...
I am trying to do a remote desktop connection between Ubuntu desktop and another Ubuntu system. I want to develop an application so it is necessary to use shell command.
ssh -X or -Y username#server_ip
I know this command is for trusted and untrusted connection between two systems but here username is necessary for connection so it is necessary to ask username and password to each user for connection. so I have created a bash file for getting input from the user. its name myscript.sh
#!/bin/bash
read -p 'Username: ' uservar
read -sp 'Password: ' passvar
sleep 10
and I want to use this variable value in another file. I wrote below code and file name terminal.sh.
#!/bin/bash<br>
xterm -e /file_path/myscript.sh
sshpass -p $passvar ssh -X $uservar#$remote_ip /usr/bin/xfce4-session
but this code is not working. I want myscript.sh user input value in terminal.sh file. one person suggests me to use signify. how to use signify here? Can anyone suggest a solution? thanks in advance.
Normally, you should set-up public/private key authentication with ssh. Anything else is a hack to get the same result.
In this case, you have to store the credentials (uid/pw) somewhere to be able to use them in your second script. That could be:
#!/bin/bash
read -p 'Username: ' uservar
read -sp 'Password: ' passvar
and call as . myscript.sh, or store them somewhere in a file for use (which is security-wise a little issue).
If you really cannot set-up your p/p-keys, you should probably put (as Inian suggests) put the prompting in the same script..
I wrote a shell script to automate mysqldump.
I don't want my password to be entered in the script file. Can anyone suggest me an alternative way to do this?
If you are running the script interactively, then you can use read to read the password into an environmental variable, and then echo that password to mysqldump.
read -s -p 'password: ' password
echo "$password" | mysqldump ...
The password will be stored in plain text in memory but not elsewhere.
Alternatively as per the documentation you can use an option file to avoid giving the password on the command line. The file would contain something similar to the below:
[client]
# The following password will be sent to all standard MySQL clients
password="my_password"
I'm trying to write a simple script to mysqldump some dbs. I'm getting stuck on the password prompt though.
I'd like to just have a config file that contains all the db creds, then the script can use those to connect to the db.
Problem is a command such as:
system('mysqldump -u username -p')
then prompts for
Enter password:
even when I do something like:
system('mysqldump -u username -p some_password')
I still get prompted for the password...
I don't do a whole lot of scripting in Ruby so I'm at a loss as to how my script can automatically enter this info so the user running the script doesn't have to.
If you already know the password why aren't you passing it to the command?
system('mysqldump -u username --password=mypassword')
you need to delete space after -p
system('mysqldump -uusername -psome_password')
or without password just
system('mysqldump -uusername')
or
system('mysqldump -uusername --password=')
you could always check the application that uses the database for the password, check the config file file for the connection string. Failing that change the password in the database.
