I'm trying to create an hierarchy of directories and files. The idea is the following : i want my script to create my directories level by level
So lets say the user types these commands from command line
/dirname #dirs=8 #levels=2
and i want it to create something like this:
/dirname
|-->/a/b
|
|-->/b/c
|
|-->/e/f
|
|-->/g/h
How can i determine the number of paths i will have in my directories
i've tried with PATH_MAX but it doesnt seem to work
#!/bin/bash
ARG_NUM=$# #argc
echo $#
if [ $ARG_NUM -ne 3 ];then
echo "Wrong number of aguments"
exit 1
fi
# ROOT_DIR
dir_name=$1
if [[ ! -d $dir_name ]]; then
mkdir $dir_name
fi
#CREATING FOLDERS WITH RANDOM NAMES
LIMIT=$3
for ((j=1; j<=LIMIT; j++))
do
mkdir -p $dir_name/$(cat /dev/urandom | tr -dc 'a-zA-Z0-9' | fold -w 8 | head -n 1)
echo $dir_name "created"
done

I have a folder structure like
base
|
|---rbbc_23434
| |------rbbp_34954
| | |___this.json
|
|---rbbc_222334
| |------rbbp_39884954
| | |___this.json
|
etc
And I want to process each this.json. Notice that the letters after rbbp are random
I have the following
#! /bin/bash
search_dir=/path/to/base/
bf="$(basename -- $search_dir)"
for entry in "$search_dir"*/
do
#echo "$entry"
f="$(basename -- $entry)"
echo "$f"
if [[ "$f" == "rbb"* ]]
then
echo "$entry"
ls "$entry""rbbp"*"/this.json"
#echo "$entry""rdgp"*"/this2.json"
#python3 something.py --input "$entry""rbbp"*"/this.json"
fi
done
With ls I can localize the this.json files from all folders but these wildcards do not seem to work when specifying a file for input to a python script or even echo
How can I specify this this.json file as a path to the something.py script?
You don't need the nested loops and if statements, just make a wildcard that matches all the directories in the path.
search_dir=/path/to/base
for file in "$search_dir"/rbb*/rbbp*/this.json
do
python3 something.py --input "$file"
done
I need to write a bash script that finds and lists symlinks from one directory (lets say some "Directory1") but only the ones pointing to files in certain another directory (lets say "Directory2"). I can`t use "find".
I have tried something like this but it's apparently wrong:
if [[ -d $1 ]]&&[[ -d $2 ]]
then
current_dir='pwd'
cd $1
do
for plik in *
if[[-L $file] && ["$(readlink -- "$file")" = "$2"] ]
then
#ls -la | grep ^l
echo "$(basename "$file")"
fi
done
fi
How about a simple ls with grep :
ls -l Directory1/ | grep "\->" | grep "Directory2"
I have found a solution:
for file1 in $_cat1/* do
if [ -L $file1]; then
dir1="$(dirname `readlink -f $file1`)"
dir2="$(dirname `readlink -f $_cat2`)"
if [dir1 == dir2]
echo $dir1
fi
fi
done
i'm trying to write a code which will print all files taking more than min_size (lets say 10G) in a directory. the problem is output off the below code is all files irrespective of the min_size. i will be getting other details like mtime , owner as well later in the code but this part itself doesnt work fine, whats wrong here ?
#!/bin/sh
if (( $# <3 )); then
echo "$0 dirname min_size count"
exit 1
else
dirname="$1";
min_size="$2";
count="$3";
#shift 3
fi
tmpfile=$(mktemp /lawdump/pulkit/files.XXXXXX)
exec 3> "$tmpfile"
find "${dirname}" -type f -print0 2>&1 | grep -v "Permission denied" | xargs -0 -I {} echo "{}" > "$tmpfile"
for i in `cat tmpfile`
do
x="`du -ah $i | awk '{print $1}' | grep G | sort -nr -k 1`"
size=$(echo $x | sed 's/[A-Za-z]*//g')
if [ size > $min_size ];then
echo $size
fi
done
Note : i know this can be done through find or du but i need to write a shell script to have an email sent out regularly with all the details.
I have searched many forums and websites to create an ALAC collection from my FLAC collection with the same directory structure with no success. Therefore I coded my own shell script and decided to share here so others can use or improve on it.
Problems I wanted to solve:
Full automation of conversion. I did not want to go and run scripts
in each and every directory.
Recursive file search
Moving all the structure from one location to another by converting flac to alac and copying the artwork. nothing else.
I did not want flac and alac files in the same directory.(which the below
script I believe can do that)
Here is how the script turned out. It works for me, I hope it does for you as well. I am using Linux Mint and bash shell.
2014-12-08 - Made some changes and now it is working fine. Before it was creating multiple copies.
Usage is: ./FLACtoALAC.sh /sourcedirectory /targetdirectory
Here are some explanations:
Source: /a/b/c/d/e/ <- e has flac
/g/f/k <- k has artwork
/l <- l has mp3
Target: /z/u/v/g/f
when the command is run : ./FLACtoALAC.sh /a/b/ /z/u/
I want the structure look like:
/z/u/v/g/f <- f was already there
/c/d/e/ <- e had flac, so created with the tree following source (/a/b)
/c/g/f/k <- k had artwork, so created with the tree following source (/a/b)
not created l <- l did not have any of the png,jpg or flac files.
I do not want to create any directory that does not contain png, jpg or flac,
unless it is a parent to one of such those directories.
Now the updated code:
#!/bin/bash
if [[ $1 ]]
then
if [[ ${1:0:1} = / || ${1:0:1} = ~ ]]
then Source_Dir=$1
elif [[ ${1:0:1} = . ]]

Try this out:
#!/bin/bash
src_dir="in"
dst_dir="out"
find ${src_dir} -type f -print0|while IFS= read -r -d '' src_file; do
dst_file=${src_file/$src_dir/$dst_dir}
echo "src_file=${src_file} dst_file=${dst_file}"
mkdir -pv `dirname $dst_file`
# use above variables and run convert command with it here
done
To test how it works:
mkdir in out
cd in
mkdir 1 2 3
find . -type d -exec touch {}/foo {}/bar {}/baz \;
cd ..
./run_my_script.sh
Now you only need to attach your convert function/script/command/whatever and improve it to read src_dir and dst_dir from the command line (I would recommend man bash - > getopts)

Script 1 giving expected o/p
[root#localhost lab]# ./test.sh
dir3
dir4
dir5
Issue is :
For script 2 , I am expecting below o/p. But there is no o/p [blank] while running .. Please help me in this.
[root#localhost lab]# ./test.sh
dir1
dir2
For the second script, you want -a ("and") instead of -o ("or"). Think the logic through: every possible string is not equal to at least one of the two, but you want to skip when it's not equal to either of them, which is to say when it's not equal to "dir1" and it's also not equal to "dir2".
