Re: string escaping in bash

[Alex fxmbsw7 Ratchev]

i need some details of peng
i wanted to make test cases for the backslashes

list=( '\one' '\\Two' '\\\Three' '\\\\four' '\\\\\five' )

which should result in output of

right=( '\one' '\Two' '\\Three' '\\four' '\\\five' )

there is collision

please review and write
especially if 'right' looks right
