Hi newbie_01,

I don't know about such custom applications, so, a custom script could be adapted to do the job.

As you can see below, for this tasks "find" command would be your friend, and combining it with desired
criterias and some other commands, you'll satisfy your requirements.

You've asked for:

1-) removing files that are x-number of days old,
Code:
# 1-) Looking for txt files older than 365 days and printing them within folder and subfolder
 find . -name "*.txt" -mtime +365

# 2-) Printing txt files modified less than 365 days ago within folder and subfolders
 find . -name "*.txt" -mtime -365

# 3-) Printing txt files modified 365 days ago within folder and subfolders
 find . -name "*.txt" -mtime 365

# 4-) Removing txt files older than 365 days within folder and subfolders
*(if you want to remove files is advisable to be sure about files listed/found by "find...")
 find . -name "*.txt" -mtime +365 -exec /bin/rm -f '{}' +

About -mtime: (-mtime n)
(+) means greater than, (-) means less than, and without any symbol means exactly equal to.

2-) Zipping files "if they are core dumped files"
*(Below examples how to zip files, but which is the characteristic of a core dumped file?)
Code:
#1-) Looking all txt files within folders and its subfolders and compress them in a unique zipped file (Compressed_Files.zip)
 find . -name "*.txt" -print | zip Compressed_Files -@

# 2--)Compressing each txt file within folder and subfolders file, adds to original name ".gz" (filename.txt to filename.txt.gz) 
# and deletes original file
 find . -name "*.txt" -exec gzip -f '{}' +

# 3-)Unzipping each txt files within folder and its subfolders, deleting original gz file.
 find . -name "*.txt.gz" -exec gunzip -f '{}' +

3-) Removing files if they are zero-sized files:
Code:
 # 1-) Removing zero size files within folder and its subfolders.
1-) find . -type f -size 0 -exec /bin/rm -f '{}' +
or
2-) find . -type f -empty -exec /bin/rm -f '{}' +

Hope it helps,

Regards.

set_color

set_color(1)							       fish							      set_color(1)

NAME

       set_color - set_color - set the terminal color

set_color - set the terminal color
   Synopsis
       set_color [-v --version] [-h --help] [-b --background COLOR] [COLOR]

   Description
       Change the foreground and/or background color of the terminal. COLOR is one of black, red, green, brown, yellow, blue, magenta, purple,
       cyan, white and normal.

       o -b, --background Set the background color

       o -c, --print-colors Prints a list of all valid color names

       o -h, --help Display help message and exit

       o -o, --bold Set bold or extra bright mode

       o -u, --underline Set underlined mode

       o -v, --version Display version and exit

       Calling set_color normal will set the terminal color to whatever is the default color of the terminal.

       Some terminals use the --bold escape sequence to switch to a brighter color set. On such terminals, set_color white will result in a grey
       font color, while set_color --bold white will result in a white font color.

       Not all terminal emulators support all these features. This is not a bug in set_color but a missing feature in the terminal emulator.

       set_color uses the terminfo database to look up how to change terminal colors on whatever terminal is in use. Some systems have old and
       incomplete terminfo databases, and may lack color information for terminals that support it. Download and install the latest version of
       ncurses and recompile fish against it in order to fix this issue.
