Ruby refused to interpolate #{dirc[3]} dispite I have tried the 
following:

system("plink -pw ppp xxx@yyyy /tmp/essai.ksh #{dirc[3]}")
system('plink -pw ppp xxx@yyyy /tmp/essai.ksh "#{dirc[3]}"')
system("plink -pw ppp xxx@yyyy /tmp/essai.ksh '#{dirc[3]}'")
system(plink '-pw ppp xxx@yyyy /tmp/essai.ksh #{dirc[3]}')
system(plink "-pw ppp xxx@yyyy /tmp/essai.ksh #{dirc[3]}")
system('plink -pw ppp xxx@yyyy /tmp/essai.ksh #{dirc[3]}')

Any suggestion please !

Thanks in advance.
