And, I'm not sure what output from rm -f is intended to be captured in /tmp/text.txt either. With -f there won't be any file not found errors, and even if there were, they would be written to stderr instead of stdout.

It might be better if those two lines were replaced by the single line:
Code:
  system("/bin/find $ar[0] ! -name '*.ext' -mtime $ar[1] -type f -print -exec rm -f  \{\} \\\; >> /tmp/text.txt 2>&1");

but I don't know if the author of this thread wants find and rm diagnostics to be on the screen or captured in the log file.

UNCRUSTIFY(1)							   User Commands						     UNCRUSTIFY(1)

NAME
uncrustify - C, C++, C#, D, Java and Pawn source code beautifier SYNOPSIS
uncrustify [OPTIONS] [FILES] DESCRIPTION
If no input files are specified, the input is read from stdin. If reading from stdin, you should specify the language using -l. If -F is used or files are specified on the command line, the output filename is PFX + "/" + filename + SFX. Unless, of course, the options --replace or --no-backup are used. When reading from stdin or doing a single file via the '-f' option, the output is dumped to stdout, unless redirected with -o FILE. Errors are always dumped to stderr OPTIONS
Basic Options: -c CFG Use the config file CFG. If not specified, uncrustify will use $UNCRUSTIFY_CONFIG or $HOME.uncrustify.cfg. -f FILE Process the single file FILE, sending output to stdout or the file specified with -o. -o FILE Redirect output to FILE. Use with -f, --update-config, --update-config-with-doc, --universalindent. -F FILE Read files to process from FILE, one filename per line. You can create this file using something like 'find . -name "*.c" > list.txt'. This cannot be combined with -f. --prefix PFX Prepend PFX to the output filename path. This cannot be combined with -f, --replace, or --no-backup. --suffix SFX Append SFX to the output filename. The default is '.uncrustify' if neither SFX or PFX are specified. This cannot be combined with -f, --replace, or --no-backup. --frag Assume the input is a code fragment and the first line is properly indented. --replace Replace source files (creates a backup). This cannot be combined with -f, --prefix, or --suffix. --no-backup Replace files, no backup. Useful if files are under source control This cannot be combined with -f, --prefix, or --suffix. --mtime Preserve mtime on replaced files. -l Language override: C, CPP, D, CS, JAVA, PAWN, VALA, OC, OC+ -t Load a file with types (usually not needed) -q Quiet mode - no output on stderr (-L will override) Config/Help Options: -h -? --help --usage Print this message and exit --version Print the version and exit --show-config Print out option documentation and exit --update-config Output a new config file. --update-config-with-doc Output a new config file with embedded usage comments. --universalindent Output a config file for Universal Indent GUI. --detect Detects the config from a source file. Use with '-f FILE'. Detection is currently fairly limited. Debug Options: -p FILE Dump debug info to a file -L SEV Set the log severity (see log_levels.h) -s Show the log severity in the logs --decode FLAG Print FLAG as text and exit EXAMPLES
Read a D file from stdin, output to stdout. cat foo.d | uncrustify -q -c my.cfg -l d Process a file, output to stdout. uncrustify -c my.cfg -d foo.d Process a source tree, output to a different tree. find src -name "*.[ch]" > files.txt uncrustify -c my.cfg -F files.txt --prefix out Process a source tree in-place. uncrustify -c my.cfg --no-backup $(find src -name "*.[ch]") NOTES
Use comments containing ' *INDENT-OFF*' and ' *INDENT-ON*' to disable processing of parts of the source file. AUTHOR
