To the shell it means: test ([]) the variable FILECOUNT for existence and if it has a value, and redirect any output to the file named '2' (> 2). If you're using the single bracket form of the tests, you'll have to use
  • -gt instead of >
  • -lt instead of <
  • -ge instead of >=
  • -le instead of <=
  • -ne instead of !=
You can get a list of all test operators by looking at the man page of test.

@dennis.jacob: the parameter '-1' to ls won't change anything. If ls detects that output does not go to a terminal it automatically switches to single-column mode. You can easily test that by running
Code:
ls | cat

in any directory.
Yes pludi, Its my mistake. Thank you for pointing that.

GO-TEST(1)						      General Commands Manual							GO-TEST(1)

NAME
go - tool for managing Go source code SYNOPSIS
go test [-c] [-i] [ build flags ] [ packages ] [ flags for test binary ] DESCRIPTION
"Go test" automates testing the packages named by the import paths. It prints a summary of the test results in the format: ok archive/tar 0.011s FAIL archive/zip 0.022s ok compress/gzip 0.033s ... followed by detailed output for each failed package. "Go test" recompiles each package along with any files with names matching the file pattern "*_test.go". These additional files can con- tain test functions, benchmark functions, and example functions. See go-testfunc(7) for more. By default, go test needs no arguments. It compiles and tests the package with source in the current directory, including tests, and runs the tests. The package is built in a temporary directory so it does not interfere with the non-test installation. OPTIONS
In addition to the build flags, the flags handled by 'go test' itself are: -c Compile the test binary to pkg.test but do not run it. -i Install packages that are dependencies of the test. Do not run the test. The test binary also accepts flags that control execution of the test; these flags are also accessible by 'go test'. See go-testflag(7) for details. For more about build flags, see go-build(1). For more about specifying packages, see go-packages(7). SEE ALSO
