Thanks, I really appritiate it.

I followed all this directions and my all command is not working now, Even ls,dir,pico too.

bash: dir: No such file or directory bash: pico: No such file or directory

When I open Terminal Window i get

bash: .bashrc: command not found bash: export: not a valid identifier

and this mfold is not working at home-rita and when i write athome-rita-downloads-mfold-3.2-RedHat-binaries-bin then i get it .-mfold: line 1: cut: No such file or directory .-mfold: line 1: awk: No such file or directory .-mfold: line 46: cat: No such file or directory .-mfold: line 1: cut: No such file or directory .-mfold: line 68 plus 1: : =: unary operator expected .-mfold: line 1: cut: No such file or directory .-mfold: line 71: : =: unary operator expected .-mfold: line 1: cut: No such file or directory .-mfold: line 73: : =: unary operator expected .-mfold: line 1: cut: No such file or directory .-mfold: line 75: : =: unary operator expected .-mfold: line 1: cut: No such file or directory .-mfold: line 77: : =: unary operator expected .-mfold: line 1: cut: No such file or directory .-mfold: line 79: : =: unary operator expected .-mfold: line 1: cut: No such file or directory .-mfold: line 81: : =: unary operator expected .-mfold: line 1: cut: No such file or directory .-mfold: line 83: : =: unary operator expected .-mfold: line 1: cut: No such file or directory .-mfold: line 85: : =: unary operator expected .-mfold: line 1: cut: No such file or directory .-mfold: line 87: : =: unary operator expected .-mfold: line 1: cut: No such file or directory .-mfold: line 89: : =: unary operator expected .-mfold: line 1: cut: No such file or directory .-mfold: line 91: : =: unary operator expected .-mfold: line 1: cut: No such file or directory .-mfold: line 93: : =: unary operator expected .-mfold: line 1: cut: No such file or directory .-mfold: line 95: : =: unary operator expected .-mfold: line 1: cut: No such file or directory .-mfold: line 97: : =: unary operator expected .-mfold: line 1: cut: No such file or directory .-mfold: line 99: : =: unary operator expected .-mfold: line 1: cut: No such file or directory .-mfold: line 101: : =: unary operator expected .-mfold: line 1: cut: No such file or directory .-mfold: line 103: : =: unary operator expected .-mfold: line 1: cut: No such file or directory .-mfold: line 105: : =: unary operator expected .-mfold: line 1: cut: No such file or directory .-mfold: line 107: : =: unary operator expected .-mfold: line 1: cut: No such file or directory .-mfold: line 109: : =: unary operator expected Invalid entry: SEQ=hairpinmirna.txt on command line.
