This solution meets the extended criteria stated in the problem.
<lang AWK>
# syntax: GAWK -f FILE_EXTENSION_IS_IN_EXTENSIONS_LIST.AWK
BEGIN {
n = split("zip,rar,7z,gz,archive,A##,tar.bz2", arr, ",")
for (i=1; i<=n; i++) {
ext_arr[tolower(arr[i])] = ""
}
filenames = "MyData.a##,MyData.tar.Gz,MyData.gzip,MyData.7z.backup,MyData...,MyData,MyData_v1.0.tar.bz2,MyData_v1.0.bz2"
n = split(filenames, fn_arr, ",")
for (i=1; i<=n; i++) {
ext_found = ""
for (ext in ext_arr) {
if (tolower(fn_arr[i]) ~ (".*\\." ext "$")) {
ext_found = ext
break
}
}
ans = (ext_found == "") ? "is not in list" : ("is in list: " ext_found)
printf("%s extension %s\n", fn_arr[i], ans)
}
exit(0)
}</lang>
