If you wrote about ENVI by rsinc it's a simple structured text file.
I attached a prototype of function.

Example of run:

octave:1> OCTAVE_VERSION
OCTAVE_VERSION = 2.1.63

octave:2> hdr=read_envi_hdr('x.hdr'); fieldnames (hdr)
{
  [1,1] = band_names
  [2,1] = bands
  [3,1] = byte_order
  [4,1] = data_type
  [5,1] = data_type_txt
  [6,1] = description
  [7,1] = file_type
  [8,1] = fwhm
  [9,1] = header_offset
  [10,1] = interleave
  [11,1] = lines
  [12,1] = samples
  [13,1] = sensor_type
  [14,1] = spectra_names
  [15,1] = wavelength
  [16,1] = z_plot_range
}
