How to take input from the user from the command line and execute commands basedon that?

Shell Programming and Scripting
1

Hi,
I am using solaris 10 and bash shell.Script execution follows below.Initially it will check whether a directory exists or not if does not exist it will create it.(This I have completed)

Second step:I have four users say user1,user2,user3,user4.Script should prompt for the user id and password.then user needs to input the userid and password.That user id should lie with in the above 4 users.if it is other than the mentioned one it should say invalid user.based on the userid and password it will be executing SVN commands(I am fine with SVN commands)

only problem here is how to take the userid and password from the user in middle of script execution.based on that script should continue the execution.

I have tried this.

[echo "Please enter userid"
read userid
if [ "$userid" = "$user1" ] || [ "$userid" = "$user2" ] || [ "$userid" = "user3" ] || [ "$userid" = "user4" ]
then
cd /export/home/mvaddadi/
svn checkout  --username $userid https://scm-coconet.com/svn/repos/vomsource/ordgen/current
else
echo "invalid id"
fi]

But it is not working.I believe read is not working properly.Thanks in Advance for your inputs.

Remove the outer-most square bracket. Its not syntactically correct.

Your tests are inconsistent. You compare first $userid with variables ($user1 and $user2) then later with strings (user3 and user4).

Thanks for your input.yeah I have remove that.when i executed the script it is throwing error like this.

Please enter userid
$ mvaddadi
mvaddadi: not found
$ read userid

It is strucking up there not going ahead furteher.

May i know how can I do that?My Ultimate requirement is if the user enter input lies in between the mentioned 4 id's I need to accept it and execute some svn command.

In case if it is another userid other than the mentioned ID I should prompt sayinng invalid userid and agian prompt for Please enter correct userid.

Thanks.

echo "Please enter userid" 
read userid 
if [[ "$userid" == "$user1" ]]
then
echo "true"
else
echo "false"
fi

It is unclear what your script looks like now. Please post its current full source.

Here is the script content.

#checking for the directories and creating them accordingly
if [ -d /export/home/vomappservers/spa ]; then
 echo "directory already exist"
else 
 mkdir -p /export/home/vomappservers/spa
fi
#link to /export/home/vomappservers/spa from /spa
ln -s /export/home/vomappservers/spa spa
if [ -d /export/home/vomappservers/spa/common/5.0 ]; then
 echo "directory already exist"
else 
 mkdir -p /export/home/vomappservers/spa/common/5.0
fi
#populating the Scripts directory from SVN
cd /export/home/vomappservers/spa/common
echo "starting checkout scripts directory"
 this is the part i am concerned about.Here need to take the userinput based on the userid entered i need to execute the svn command and need to pass the user entered userid parameter to SVN command.In short with the useried enters i need to execute the svn command.It should allow only 4 users[this i can choose like user1,user2,user3,user4]
echo "Please enter your urerid  followed by [ENTER]:"
$userid=$1
svn checkout  --username $1 https://scm-coconet.com/svn/repos/vomsource/sourcecode/vomappaservers/spa/common/scripts
echo "completed https://scm-coconet.com/svn/repos/vomsource/sourcecode/vomappaservers/spa/common/scripts
 
some other commands like creating links followed

[/code]

Thanks for your response.

Please post the whole script content and only it, i.e. without broken comments or whatever.

In any case, this is bogus:

$userid=$1

Should be

userid=$1

You didn't correct the issue I reported in post #3

Could you please let me know how can I change that to two users like you have suggested?I have made followin changes to the code to test whether at least for one userid it is allowing or not.

 #populating the Scripts directory from SVN
    41  cd /export/home/vomappservers/spa/common
    42  pwd
    43  echo "starting checkout scripts directory"
    44  echo "Please enter your urerid  followed by [ENTER]:"
    45  userid=$1
    46  read userid
    47  if [ "$userid" = "$mvaddadi" ]
    48  then
    49  svn checkout  --username $1 https://scm-coconet.capgemini.com/svn/repos/vomsource/sourcecode/vomappaservers/spa/common/scripts
    50  echo "completed https://scm-coconet.capgemini.com/svn/repos/vomsource/sourcecode/vomappaservers/spa/common/scripts directory"
    51  else
    52  echo "invalid id please provide the valid userid"
    53  fi

i have just tried a dry run of the script it has thrown folloing error:

$ ./testscript.sh

ln: cannot create spa/spa: File exists
