Hi,
thanks to everyone for replying however I think i failed to define the
problem accurately :
i have files assigned to @files variable :
2168a5_vow_band_1.fea
169b2_vow_band_1.fea
2168d6_vow_band_1.fea
2168d5_vow_band_1.fea
169g3_vow_band_1.fea
neutral.txt
And i want the files say for eg suffix d and 1 and with extension fea.The
thing is if i try to match d all will get matched for obvious reason.
basically I wanna generate the same output as of the following command on
shell prompt :
ls ???[g][^1] *.fea
** will generate all files whose 4th char is g followed by character which
is not 1.
ls ???[^g][^1] *.fea
Many Thanks....please do send in ur replies.
