shell script to verify brackets

Hi ,

I am trying to write a shell script to verify if brackets are used correctly in a file . If there is some other format it should show invalid.

Below are the correct formats :

[sunil:/1/2]
[sagar:/1/2/3/4]

Incorrect formats may have format :
[sunil:/1/2]]
[[sagar:/1/2]
[[sunil:/1/2/3]]

Please advise .

if grep -qv "^\[[a-z].*[0-9]\]$" /path/to/your/file
then
      echo "File contains invalid characters"
fi
