Why ls colors two supposedly similar files differently?












0















So, here's the peculiar situation:



$ ls -l foo.sqlite foo.ssqlite
-rw-r--r-- 1 xie xie 8192 Jan 22 19:25 foo.sqlite
-rw-r--r-- 1 xie xie 8192 Jan 23 11:48 foo.ssqlite


In the output, foo.sqlite is colored blue by ls whle foo.ssqlite is colored red/pink. Permissions are the same, types are the same:



$ file foo.sqlite foo.ssqlite
foo.sqlite: SQLite 3.x database, last written using SQLite version 3026000
foo.ssqlite: SQLite 3.x database, last written using SQLite version 3023001


The only obvious difference is that foo.sqlite was created by a Perl script, while the other - by Python script, however that does not explain the different coloring, as if ls recognizes these as two different file types. Well, the question then is why ls reports these in different color despite the type being the same ?
