That for loop with cat is not recommended

You should use a while loop instead, try something like:
Code:
#!/bin/bash

while IFS="," read v1 v2 v3 v4 v5
do
        printf "%s\n" "$v2"
        printf "%s,%s,%s,%s,%s\n" "$v1" "$v2" "$v3" "$v4" "$v5"
done < src.src

mlib_SignalEmphasize_S16_S16_Sat(3MLIB) 		    mediaLib Library Functions			   mlib_SignalEmphasize_S16_S16_Sat(3MLIB)

NAME

       mlib_SignalEmphasize_S16_S16_Sat, mlib_SignalEmphasize_S16S_S16S_Sat, mlib_SignalEmphasize_F32_F32, mlib_SignalEmphasize_F32S_F32S - signal
       pre-emphasizing

SYNOPSIS

       cc [ flag... ] file... -lmlib [ library... ]
       #include <mlib.h>

       mlib_status mlib_SignalEmphasize_S16_S16_Sat(mlib_s16 *dst, const mlib_s16 *src, void *filter, mlib_s32 n);

       mlib_status mlib_SignalEmphasize_S16S_S16S_Sat(mlib_s16 *dst, const mlib_s16 *src, void *filter, mlib_s32 n);

       mlib_status mlib_SignalEmphasize_F32_F32(mlib_f32 *dst, const mlib_f32 *src, void *filter, mlib_s32 n);

       mlib_status mlib_SignalEmphasize_F32S_F32S(mlib_f32 *dst, const mlib_f32 *src, void *filter, mlib_s32 n);

DESCRIPTION

       Each of these functions applies the preemphasizer to one signal packet and updates the filter states.

       For monaural signals, the following equation is used:

       dst[i] = src[i] - alpha*src[i - 1]

       where i = 0, 1, ..., (n - 1); src[-1] = 0.

       For stereo signals, the following equation is used:

       dst[2*i]     = src[2*i]	   - alpha*src[2*(i - 1)]
       dst[2*i + 1] = src[2*i + 1] - alpha*src[2*(i - 1) + 1]

       where i = 0, 1, ..., (n - 1); src[-2] = src[-1] = 0.

PARAMETERS

       Each of the functions takes the following arguments:

       dst	       Destination signal array.

       src	       Source signal array.

       filter	       Internal filter structure.

       n	       Number of samples in the source signal array.

RETURN VALUES

       Each of the functions returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.

ATTRIBUTES
