-e turns on to interpret escape sequences (-E disables)
\033 is the hexadecimal representation of ASCII 027, which is the escape code
Thinking back to early programming days, we would often send an escape character followed by other characters to turn on a function. For instance to make something bold, change color, change spacing.
Thus, my thinking is that the first code
[0;32m is to turn on something, while
\033[m is the escape character and a code to turn it back off.
I do not recognize either segment. Then again, it has been a long time since I had to send escape sequences to output (screen, printer) devices.

sjtoeuc
jistoeuc(1) User Commands jistoeuc(1)
NAME
jistoeuc, jistosj, euctojis, euctosj, sjtojis, sjtoeuc - Code conversion between JIS, PC kanji, and Japanese EUC
SYNOPSIS
jistoeuc [-8] [-U] [filename...]
jistosj [-8] [-U] [filename...]
euctojis [-8] [-U] [filename...]
euctosj [-U] [filename...]
sjtojis [-8] [-U] [filename...]
sjtoeuc [-U] [filename...]
AVAILABILITY
SUNWjfpu
DESCRIPTION
For Japanese language handling, the jistoeuc family provides conversion between different code standards. command [ filename ...] does the
specified conversion on the contents of the input filenames and writes it to stdout.
If filename is not given, it reads and converts characters from the standard input.
jistoeuc converts JIS to Japanese EUC
jistosj converts JIS to PC kanji
euctojis converts Japanese EUC to JIS
euctosj converts Japanese EUC to PC kanji
sjtojis converts PC kanji to JIS
sjtoeuc converts PC kanji to Japanese EUC
OPTIONS
-8 With this option specified, the commands jistoeuc, jistosj, sjtojis, and sjtoeuc, can support JIS X 0201 (Half-Size Katakana).
This 8-bit JIS code does not use ISO Shift-In and Shift-Out escape sequences.
-U The output is not buffered (The default is buffered output).
SEE ALSO
iconv(1), iconv_ja(5)
NOTES
This command can handle shift-in escape sequences for the following character sets:
JIS X 0208 shift-in escape - E$B, E$(B, E$@
JIS X 0212 shift-in escape - E$(D
JIS X 0201 Roman shift-in escape - E(J, E(H
ASCII shift-in escape - E(B
euctojis and sjtojis can handle shift-in escape sequences for the following character sets:
JIS X 0208 shift-in - E$B
JIS X 0212 shift-in - E$(D (except when sjtojis command is specified)
JIS X 0201 Roman shift-in - E(J
jistoeuc does not check whether or not each code in the input file is correct. Conversion with PC kanji is not based on TOG Japanese Ven-
dors Council (TOG/JVC) Recommended Code Set Conversion Specification between Japanese EUC and Shift-JIS. The iconv(1) utility provides
these functions. See iconv(1) and iconv_ja(5) for more information.
BUGS
If JIS X 0212 character set is specified as input, jistosj and euctosj can not support the conversion correctly. euctosj, sjtoeuc, jis-
tosj, and sjtojis can support conversion correctly only if JIS X 0208 1 ku - 84 ku is specified as input.
