These cups do not runneth over.

The Little Prince – A photo series by Matej Peljhan

Muscular dystrophy is a disorder that weakens a person’s muscles over time. Those who have the disease gradually lose the ability to do things people normally take for granted—such as walking, playing basketball, dancing and even swimming.

A photographer based in Slovenia named Matej Peljhan took photos of a  12-year-named Luka who suffers from muscular dystrophy depicting the child doing things he’s unable to because of his condition. After talking to Luka about his wish to do activities boys his age enjoy like skateboarding and swimming, the photographer created the non-digitally manipulated series which both show sense of humor and an undying spirit. Rather than use some type of digital trickery to make this dream a reality, Peljhan decided to simply use a different perspective.

Created by laying cloth and everyday objects on the ground, and photography trickery, Peljhan helped Luka turn his dreams (and drawings from a notebook) into reality.

These poignant pictures also send a message about the disorder, and remind viewers to appreciate life and live it to the fullest.

How to check if a directory exists in a shell script

To check if a directory exists and is a directory use the following syntax:

[ -d "/path/to/dir" ] && echo "Directory /path/to/dir exits." || echo "Error: Directory /path/to/dir does not exits."

The following version also check for symbolic link:

[ -d "/path/to/dir" && ! -L "/path/to/dir" ] && echo "Directory /path/to/dir exits." || echo "Error: Directory /path/to/dir exits but point to $(readlink -f /path/to/dir)."

OR

[ -d "/path/to/dir" && ! -h "/path/to/dir" ] && echo "Directory /path/to/dir exits." || echo "Error: Directory /path/to/dir exits but point to $(readlink -f /path/to/dir)."

Finally, you can use the traditional if..else..fi:

if [ -d "/path/to/dir" ]
then
    echo "Directory /path/to/dir exits."
else
    echo "Error: Directory /path/to/dir does not exits."
fi

Shell script examples to see if a ${directory} exists or not

 
#!/bin/bash
dir="$1"

[ $# -eq 0 ] && { echo "Usage: $0 dir-name"; exit 1; }

if [ -d "$dir" -a ! -h "$dir" ]
then
   echo "$dir found and setting up new Apache/Lighttpd/Nginx jail, please wait..."
   # __WWWJailSetup "cyberciti.biz" "setup"
else
   echo "Error: $dir not found or is symlink to $(readlink -f ${dir})."
fi

In this example, create directories if does not exits:

# Purpose: Setup jail and copy files
# Category : Core
# Override : No
# Parameter(s) : d => domain name
#                action => setup or update
__WWWJailSetup(){
        local d="$1"
        local action="${2:setup}"       # setup or update???
        local index="$d

$d

" # default index.html
        local J="$(_getJailRoot $d)/$d" # our sweet home 
        local _i=""

        [ "$action" == "setup" ] && echo "* Init jail config at $J..." || echo "* Updating jail init config at $J..."
        __init_domain_config "$d"

        [ "$action" == "setup" ] && echo "* Setting up jail at $J..." || echo "* Updating jail at $J..."
        [ ! -d "$J" ] &&  $_mkdir -p "$J"

        for _i in $J/{etc,tmp,usr,var,home,dev,bin,lib64}
        do
                [ ! -d "$_i" ] &&  $_mkdir -p "$_i"
        done
        for _i in $_lighttpd_webalizer_base/$d/stats/{dump,out}
        do
                [ ! -d "$_i" ] &&  $_mkdir -p "$_i"
        done
        for _i in $_lighttpd_webalizer_prepost_base/$d/{pre.d,post.d}
        do
                [ ! -d "$_i" ] &&  $_mkdir -p "$_i"
        done
## truncated 
}

Summary

Use the following to check file/directory types and compare values:

  1. -L "FILE" : FILE exists and is a symbolic link (same as -h)
  2. -h "FILE" : FILE exists and is a symbolic link (same as -L)
  3. -d "FILE" : FILE exists and is a directory
  4. -w "FILE" : FILE exists and write permission is granted
