How do I send pipes and regex from Vim to bash shell? -

i know how pass pipes vim bash.... p.e.

this command works in bash shell:

$ sort -k2n -t'|' /cygdrive/d/test55.txt 

if open text file in vim , apply same command

:%!sort -k2n -t'|' 

it gives error:
''' not recognized internal or external command, operable program or batch file.

same problem regex. isn't possible pass regex vim bash?
p.e.

:%!sort -k3 -t'\a\{3,}' 

(sort after 3rd time word longer 3 characters)

or

:%!sort -k3 -t'[,;]' 

(sort after 3rd time ',' or ';' found)

1) how can pass pipes bash?
2) how can send regex bash?
