Spaces behaviour in shell
Hello,

I am a bit puzzled by the way my shell treats spaces in filenames.

An example will be way clearer than any explanation I can make:
Code:
$ ls test\ file\ with\ spaces
test file with spaces
$ var="test\ file\ with\ spaces"
$ echo $var
test\ file\ with\ spaces
$ ls $var
ls: cannot access test\: No such file or directory
ls: cannot access file\: No such file or directory
ls: cannot access with\: No such file or directory
ls: cannot access spaces: No such file or directory

The problem is the same if I am using double quotes around the filename or when I nest a command displaying the filename.

I've been crawling on the internet for a long time, but I haven't been able to find any documentation on this particular issue.

pg_test_fsync

PG_TEST_FSYNC(1)					  PostgreSQL 9.2.7 Documentation					  PG_TEST_FSYNC(1)

NAME

       pg_test_fsync - determine fastest wal_sync_method for PostgreSQL

SYNOPSIS

       pg_test_fsync [option...]

DESCRIPTION

       pg_test_fsync is intended to give you a reasonable idea of what the fastest wal_sync_method is on your specific system, as well as
       supplying diagnostic information in the event of an identified I/O problem. However, differences shown by pg_test_fsync might not make any
       difference in real database throughput, especially since many database servers are not speed-limited by their transaction logs.

OPTIONS

       pg_test_fsync accepts the following command-line options:

       -f, --filename
	   Specifies the file name to write test data in. This file should be in the same file system that the pg_xlog directory is or will be
	   placed in. (pg_xlog contains the WAL files.) The default is pg_test_fsync.out in the current directory.

       -s, --secs-per-test
	   Specifies the number of seconds for each test. The more time per test, the greater the test's accuracy, but the longer it takes to run.
	   The default is 2 seconds, which allows the program to complete in about 30 seconds.

       -V, --version
	   Print the pg_test_fsync version and exit.

       -?, --help
	   Show help about pg_test_fsync command line arguments, and exit.
