SYNOPSISnumprocess [-dhV] /<expression>/ [FILE or STDIN]
| numprocess [-dhV] /<expression>/ (Input on STDIN from pipeline.)
numprocess [-dhV] /<expression>/ (Input on STDIN. Use Ctrl-D to stop.)
DESCRIPTIONnumprocess will take as one argument, a list of operations to be performed on numbers that it encounters. It will perform those operations on each number and return the result in place of the original number.
Add 1 to all numbers. $ numprocess /+1/ file1 Convert all numbers from miles to kilometers. Multiply by 8 and divide by 5. $ cat file1 | numprocess /*8,%5/ Convert from celcius to fahreheit degrees. Multiply by 9, divide by 5 and add 32. $ numprocess /*9,%5,+32/ temperatures Find the area of each circle from the given radius. $ numprocess /^2,*pi/ radii
KEYWORDS AND OPERATORS
For operators, the modifying number goes directly after the operator, with the exception of functions like sqrt, sin, cos, etc. + Addition - Subtraction * Multiplication % Division ^ Power function sqrt Square Root (*) sin Sine function cos Cosine function Constants and keywords that can be used pi 3.141592654 e 2.718281828 (*) When using the sqrt operation on negative numbers, it will take the absolute value of the number, sqrt it and then tack an i on the end of the result to signify that the resulting number is imaginary.
-h Help: You're looking at it. -V Increase verbosity. -d Debug mode. For developers
BUGSThere is currently no way to take the number found in the text stream and use it as the numerator instead of the denominator of a division operation.
