Hi perl monks...
Please suggest me how to search and substitute for word with special characters without using back slashes..
my @nets = "in1_, in1_";
since variable nets contains auto generated words, sometimes it may contain simple words without any special variables as follows
my @nets = "a_c, b_c, N_05";
lets say my file has in1_ word at many lines of codes and i wrote a perl script to search for in1_ i.e. $nets word and replace it with in1_1 word i.e. $nets1...
print "substitution is done" if (s/$nets/$nets/);
But, while executing the script i understood that special characters  are present in variable nets, hence this substitution regex statement is not working... i read that i have to use back slashes for those characters... since nets file will be auto generated and sometimes only it may contain array values, how can i generalize this regex script accordingly...
