How to check if a filename in a directory starts with a certain string
Hello,

Trying to iterate over set of file in current directory and check if the file name in that folder matches certain string. This is what I have so far. Here I am checking if the file name starts with nexus, if so echo file name to log file.
Getting weird syntax errors. Any help is appreciated
Code:
for filename in ./*
 do	

   if [ -f "$filename" ];   
       then
	    file="${filename#*/}";
	    if [["$file"==*nexus]];
	    then               
          	 echo $file >> test.log     
  	    fi   
   fi   
 done;

Although I haven't tested this, or your code, and because I don't know what shell you are using, and because it's too late in the evening to play "Let's guess the error message"
Code:
if [[ "$file" =~ ./nexus* ]];

Hi Scott,

It's failing with the following error. BTW, it's bash shell.

Code:
Command '"./test.sh"'
failed with return code 2 and error message
./test.sh: line 11: syntax error in conditional expression: unexpected token `;'
./test.sh: line 11: syntax error near `;'
./test.sh: line 11: `	    if [[ "$filename" =~ nexus*]];'.

            if [[ "$file" == "*nexus" ]]

            fi
   fi
 done;

Hi Prince of Persia,

That eliminated the syntax errors, but it's not matching the file name....
I have in the directory a file name like nexus-55511533

It's not able to match the filename....and therefore the echo is not working.

That's because your logic/comparison is faulty.

Code:
if [[ "$file" == nexus* ]]
