-if_fs, -not_if_fs¶

Introduction¶

The -if_fs option is the same as the the -if option except it takes "fixed strings" rather than extended regular expressions. The -not_if_fs is the same as the -not_if option except it takes "fixed strings".

The "fixed string" options have the advantage that matches do not use the regex wildcards. For example, "-if 3.0" will match "300" because the period is a wildcard character that matches any character including a zero.

Usage¶

-if_fs X
-not_if_fs X

X is a fixed string (not a regular expression)

See also: -if, See also: -not_if, See also: -not_if_fs,

Description: if X if X (fixed string), conditional execution on match
