You could try this file exchange submission.
If that doesnt work, please update your question with more details:
  • What is 'bad line correction'?
  • Link to a description of what ENVI files are, hopefully with the format details
  • What you mean by 'good image'. Are you getting the data, but its not interleaved right? Or are you getting the wrong data type, or something else.
  • Format the code and add comments, so that its easier for people to read. (I dont know why you are modifying the values in the for loop.)

"bad line correction means if there are no values in any column for the bands and we average the value by the adjacent ones.
*envi files are BSQ,BIL,BIP
*good image means from which i can visualize the objects. like buildings roads etc.

ENVI files are classified by their header file, which contains information on how many bands, which wavelengths and the x-y resolution. Example: 400*400 resolution, with 250 spectral bands in the visual spectrum.
