Syntax for regex in IF statment

  • 772

I'm trying to come up with the syntax for a regex in an IF statement, but I'm not quickly having success... Can anyone lend a quick hand please?

if [[ "$path/$file" =~ .{txt,doc,docx,xlsx,rtf} ]];
   then
    echo "hello"
fi
bash

    That's pretty close to a glob pattern. Try

    if [[ "$path/$file" == *.{txt,doc,docx,xlsx,rtf} ]];

    If you really want a regular expression

    if [[ "$path/$file" =~ \.(txt|doc|docx|xlsx|rtf)$ ]];

    Finding a regular expression tutorial online left as an exercise ...
