The first line sends fd 1 and fd 2 into your file. After that first line, put the lines that need to output to your file. Then use my second line which restores fd 1 and fd 2 to what they were originally.

The first line saves fd 1 and 2 by copying then to fd 4 and 5. The second line copies them back. The construct "4>&-" closes fd 4.

NAME

       libmcrypt-config - script to get information about the installed version of	LIBMCRYPT.

SYNOPSIS

       libmcrypt-config [  --prefix[=DIR]  ] [	--exec-prefix[=DIR]  ] [  --libs  ] [  --cflags  ] [  --version  ]

       use LIBMCRYPT library.

OPTIONS

	      If specified, use PREFIX instead of the installation prefix that LIBMCRYPT was built with when computing the output for the --cflags
	      and  --libs  options. This option is also used for the exec prefix if --exec-prefix was not specified. This option must be specified
	      before any --libs or --cflags options.

       --exec-prefix=PREFIX
	      If specified, use PREFIX instead of the installation exec prefix that LIBMCRYPT was built with when computing  the  output  for  the
	      --cflags and --libs options. This option must be specified before any --libs or --cflags options.

       --libs Print the linker flags that are necessary to link a LIBMCRYPT program.
