The '-v' option to cygstart gives the key to understanding this by showing what actually gets passed along by cygstart. WORKS: davec@SodiumWin ~ $ cygstart -v bash -c " ' echo TT; sleep 5 ' " ShellExecute(NULL, "(null)", "bash", "-c ' echo TT; sleep 5 ' ", "(null)", 1) The quotes surrounding the argument to -c get passed along to the executed bash. WORKS: davec@SodiumWin ~ $ cygstart -v bash -c '"echo 1;read"' ShellExecute(NULL, "(null)", "bash", "-c "echo 1;read"", "(null)", 1) Same here, the echo and read are both contained in one argument to -c. DOES NOT WORK davec@SodiumWin ~ $ cygstart -v bash -c 'echo\ 1;read' ShellExecute(NULL, "(null)", "bash", "-c echo\ 1;read", "(null)", 1) Without the quotes to group the echo and read together, when the executed bash breaks the line up into words, the -c only sees echo\ as its command. WORKS: davec@SodiumWin ~ $ cygstart -v bash -c \'echo 1\;read \' ShellExecute(NULL, "(null)", "bash", "-c 'echo 1;read '", "(null)", 1) By escaping the quotes and semicolon so they get passed along intact, the executed bash also gets an intact command string.
