Problems with sudo inside shell script

rated 0 times [ 2] [ 0] / answers: 1 / hits: 936 / 1 Year ago, fri, january 27, 2023, 6:51:21

I want to make a shell script to run VI with sudo if I try to edit a file that I don't have write permissions and for that I created an alias

    alias vi=my_script.sh



    #!/bin/bash

    file=$1



    if [ -r $file ]

    then

       /usr/bin/vi $file

    else

       sudo /usr/bin/vi $file

    fi

However, no matter what, when try to edit, let's say /etc/hosts, I still not being allowed to edit it.

What am I doing wrong?

I have modified your script to work

#!/bin/bash

file=$1

wown=$(/bin/ls -alF $file | awk '{print $3}')



if [ -r $file ] && [ $wown == $USER ]

then

    /usr/bin/vi $file

else

    sudo /usr/bin/vi $file

fi

And if you wish to access it directly from anywhere, you can put it in PATH (like ~/bin/) rather than making an alias for it.
