# Sort the output:
|
|
|
# 1) sed: remove first 9 lines
|
|
|
# 2) sed: remove everything before the first slash in every other line (package names), including the slash itself
|
|
|
# 3) sed: remove version number strings in every other line (all numbers after the first space after package names
|
|
|
# 4) sed: remove bracket mark ) from every other line
|
|
|
# 5) perl: colorize the output: every other line with bold blue ( \033[1:34m ) and the other after that with dim yellow ( \033[0;33m ). Starting from the first output line (sorted by sed in the first step)
|
|
|
# 6) sed: colorize all '[installed]' strings with bold red ( [ \033[1;31m )
|
|
|
# 7) echo: normalize bash text (reset colors with \e[0m)
|
|
|
# NOTE: \e and \033 mean the same thing.
