Hi nezabudka,
Note that most Solaris systems don't have the -regex, -path, and -not primaries.

Hi snowfrost88,
The find command that you're using has two groups of primaries separated by a logical OR operator (-o). The first group of primaries is just -name "*.txt". This group essentially finds all files with names ending with .txt and ignores them. The second group finds all files with names ending with .err that have been modified in the last 30 days that are not directories and that have the name ./b and moves all files that meet all of those requirements to the file named ./c (which we hope, but have not verified, is a file of type directory). Since no filename can ever contain a <slash> character, no filename can ever be selected by the -name ./b primary (and, therefore, no files will ever be moved by this command).

In addition to the problem noted above, I assume that what you're really trying to do is to move all files that have been modified within the last 30 days that either have a name ending in .txt or ending in .err that are not located in or under a directory named either b or c into the directory named c without duplicating any of the file hierarchy structure into the directory c. If that assumption is correct, you probably want something more like:

Code:

find . \( -type d \( -name b -o -name c \) -prune \) -o \( -type f -mtime -30 \( -name '*.txt' -o -name '*.err' \) -exec mv {} c/ \; \)

Note the sets of \( and \) grouping operators to alter the precedence the logical OR operators and the -prune primary to ignore all files under directories named b or c when selecting regular files with the extensions .txt and .err.
