Searching for a pattern between 2 semicolons
I have logs which is having strings like below,
Code:
errorMsg;;
errorMsg;bad input;

so I need to grep from logs file which searches for errorMsg followed by semicolon followed by any text and then ending again with semicolon.

More importantly, I should not get errorMsg and having nothing inside the 2 semicolons. I should get results having something between the 2 semicolons. Please help me with the grep or any other for searching this.

Thanks in advance.

Thank you !

And one more question -

I need to search for lines having the string "exec_error" but not having the strings "Web site/page/script" and "Illegal loop"

For eg from below log file, I need to get only the 1st line and not the 2nd line and 3rd lines,

Code:
 
exec_error: Invalid file format
exec_error: Web site/page/script 
exec_error: Illegal loop
