cleanlinks(1) General Commands Manual cleanlinks(1)NAME
cleanlinks - remove dangling symbolic links and empty directories
SYNOPSIS
cleanlinks
DESCRIPTION
The cleanlinks program searches the directory tree descended from the current directory for symbolic links whose targets do not exist, and
removes them. It then removes all empty directories in that directory tree.
cleanlinks is useful for cleaning up a shadow link tree created with lndir(1) after files have been removed from the real directory.
DIAGNOSTICS
A message will be printed upon encountering each dangling symlink and empty directory.
SEE ALSO lndir(1).
AUTHOR
David Dawes wrote the cleanlinks program for XFree86.

lndir(1X)lndir(1X)NAME
lndir - create a shadow directory of symbolic links to another directory tree
SYNOPSIS
lndir fromdir [todir]
DESCRIPTION
lndir makes a shadow copy todir of a directory tree fromdir, except that the shadow is not populated with real files but instead with sym-
bolic links pointing at the real files in the fromdir directory tree. This is usually useful for maintaining source code for different
machine architectures. You create a shadow directory containing links to the real source which you will have usually NFS mounted from a
machine of a different architecture, and then recompile it. The object files will be in the shadow directory, while the source files in
the shadow directory are just symlinks to the real files.
This has the advantage that if you update the source, you need not propagate the change to the other architectures by hand, since all
source in shadow directories are symlinks to the real thing: just cd to the shadow directory and recompile.
The todir argument is optional and defaults to the current directory. The fromdir argument may be relative (e.g., ../src) and is relative
to todir (not the current directory).
Note that RCS, SCCS, and CVS.adm directories are not shadowed.
Note also that if you add files, you must run lndir again. Deleting files is difficult because the symlinks will point to places that no
longer exist.
BUGS
The patch routine needs to be able to change the files. You should never run patch from a shadow directory.
Use a command like the following to clear out all files before you can relink (if the fromdir has been moved, for instance):
find todir -type l -print | xargs rm
The following command will find all files that are not directories:
find . ! -type d -print

I need to use bash to convert sentences where all words start with a small letter into one where all words start with a capital letter.
So that a string like:

Hi,
What is installation package and how to create it?
When we run:
in AIX:
installp package1
or
in Linux
rpm -ivh mypackage
What is package1 or mypackage in the abov examples and how to create them and deploy them?
I hope my question is clear enough.

What is the point of this? Whenever I close my shell it appends to the history file without adding this. I have never seen it overwrite my history file.
# When the shell exits, append to the history file instead of overwriting it

After the success of the jq - tool for parsing and manipulating JSON-Data someone wrote a tool called yq, which aims to be the same for YAML, what jq is for JSON. Seems to work fine. I'll definitely give it a chance in future.
