====== Nice Scripts ======
===== Welcome to Shell Scripting! =====
==== Parsing Configs ====
The file.csv file content is :
<file>
user0001;password0001;user0002;password0002
user0011;password0011;user0012;password0012 ...
</file>

And the shell program is just :
  { while IFS=';' read u1 p1 u2 p2; do imapsync --user1 $u1 --password1
  $p1 --user2 $u2 --password2 $p2 ... done ; } < file.csv

==== Bash Readarray ====

Better than the above ''while read'' loop is the use of Bash's builtin
''readarray'' as it allows to avoid spawning a sub-shell and therefore variable
assignments from inside the loop work.
