Item Limit
Characters in a character class 2^(number of bits per byte)
Length of input record MAX_INT
Length of output record Unlimited
Length of source line Unlimited
Number of fields in a record MAX_LONG
Number of file redirections Unlimited
Number of input records in one file MAX_LONG
Number of input records total MAX_LONG
Number of pipe redirections min(number of processes per user, number of open files)
Numeric values Double-precision floating point (if not using MPFR)
Size of a field MAX_INT
Size of a literal string MAX_INT
