Separate Directories from Files with "----" Bash Scripting - bash

I want to separate directories from files in a list. I would like them to appear as follows:
DirectoryName1
DirectoryNameA
DirectoryName_Two
--
FileName1
FileNameA
FileName_Two
Basically, I want two or three dashes in between my directories and files.
Here is what the following code looks like.
DirectoryName1
DirectoryNameA
DirectoryName_Two
FileName1
FileNameA
FileName_Two
Here is my code:
#!/bin/bash
if [[ $# -ge 1 ]]; then
cd "$1" 2> /dev/null
if [[ $? = 1 ]]; then
echo "Please enter a valid directory."
else
ls -a | sort -k 1 | awk '{printf "(%d) %s\n", NR, $0;}'
fi
else
ls -a | sort -k 1| awk '{printf "(%d) %s\n", NR, $0;}'
fi

Here's one possible solution:
#!/bin/bash
if [[ $# -ge 1 ]]; then
dir_to_list=$1
if [[ ! -d ${dir_to_list} ]]; then
echo "Please enter a valid directory."
exit
fi
else
dir_to_list="."
fi
files=`ls --group-directories-first $dir_to_list`
DIRS="TRUE"
i=0
for f in ${files}; do
if [[ ${DIRS} == "TRUE" && ! -d ${dir_to_list}/${f} ]]; then
# First non-directory entry
echo ----
DIRS="FALSE"
fi
(( i++ ))
echo ${i}. ${f}
done
Cheers
Update: fixed bug for listing other directories

bash script loop to check if variable contains string - not working

i have a script which copy files from one s3 bucket to local server, do some stuff and upload it to another s3 bucket.
in the original bucket i have few folders, one of them called "OTHER"
i dot want my script to work on this folder
i tried to define a loop to check if the path string does not contains the string "OTHER" only then to continue to other commands but for some reason it is not working.
what am i doing wrong ?
#!/bin/bash

You need to use the double-bracket conditional command to turn == and != into pattern matching operators:
if [[ "$j" != *"OTHER"* ]]; then
# ^^ ^^
Or use case
case "$j" in
*OTHER*) ... ;;
*) echo "this is like an `else` block" ;;
esac
Paste your code into https://www.shellcheck.net/ for other things to fix.
I think glenn jackman was on the right path. Try this:
if [[ "$j" != *OTHER* ]]; then
The [[ ]] is required for pattern string matching (and you have to remove the " ). The case statement is also a good idea. You can abandon the shell test altogether and use grep as follows:
if
grep -q '.*OTHER.*' <<< "$j" 2>/dev/null
then
...
fi
Here's a check of the [[ ]]:
$ echo $j
abOTHERc
$ [[ "$j" == *OTHER* ]]
$ echo $?
0
As per BenjaminW., the quotes around $j in [[ ]] are unnecessary. However, the quotes around *OTHER* do make a big difference. See below:
$ j="OTHER THINGS"
$ [[ $j == "*OTHER*" ]] ; echo "$j" matches '"*OTHER*"': $?
OTHER THINGS matches "*OTHER*": 1
$ [[ $j == *OTHER* ]] ; echo "$j" matches '*OTHER*': $?
OTHER THINGS matches *OTHER*: 0

Bash - sometimes creates only empty output

I am trying to create a bash dictionary script that accepts first argument and creates file named after that, then script accepts next arguments (which are files inside same folder) and outputs their content into file (first argument). It also sorts, deletes symbols etc., but main problem is, that sometimes ouptut file is empty (I am passing one non empty file and one non existing file), after deleting and running script few more times it is sometimes empty sometimes not.
#!/bin/bash
numberoffileargs=$(( $# - 1 ))
exitstat=0
counterexit=0
acceptingstdin=0;
> "$1";
#check if we have given input files given
if [ "$#" -gt 1 ]; then
#for cycle going through input files
for i in "${#:2}"
do
#check whether input file is readable
if [ -r "${i}" ]; then
cat "${i}" >> "$1"
#else redirect to standard output
else
exitstat=2
counterexit=$((counterexit + 1))
echo "file does not exist" 1>&2
fi
done
else
echo "stdin code to be done"
acceptingstdin=1
#stdin input to output file
#stdin=$(cat)
fi
#one word for each line, alphabetical sort, alphabet only, remove duplicates
#all lowercase
#sort -u >> "$1"
if [ "$counterexit" -eq "$numberoffileargs" ] && [ "$acceptingstdin" -eq 0 ]; then
exitstat=3
fi
cat "$1" | sed -r 's/[^a-zA-Z\-]+/ /g' | tr A-Z a-z | tr ' ' '\n' | sort -u | sed '/^$/d' > "$1"
echo "$numberoffileargs"
echo "$counterexit"
echo "$exitstat"
exit $exitstat
Here is your script with some syntax improvement. Your trouble came from the fact that the dictionary was both on input and output on your pipeline; I added a temp file to fix it.
#!/bin/bash
(($# >= 1)) || { echo "Usage: $0 dictionary file ..." >&2 ; exit 1;}
dict="$1"
shift
echo "Creating $dict ..."
>| "$dict" || { echo "Failed." >&2 ; exit 1;}
numberoffileargs=$#
exitstat=0
counterexit=0
acceptingstdin=0
if (($# > 0)); then
for i ; do
#check whether input file is readable
if [ -r "${i}" ]; then
cat "${i}" >> "$dict"
else
exitstat=2
let counterexit++
echo "file does not exist" >&2
fi
done
else
echo "stdin code to be done"
acceptingstdin=1
fi
if ((counterexit == numberoffileargs && acceptingstdin == 0)); then
exitstat=3
fi
sed -r 's/[^a-zA-Z\-]+/ /g' < "$dict" | tr '[:upper:]' '[:lower:]' | tr ' ' '\n' |
sort -u | sed '/^$/d' >| tmp$$
mv -f tmp$$ "$dict"
echo "$numberoffileargs"
echo "$counterexit"
echo "$exitstat"
exit $exitstat
The pipeline might be improved.

Bash script loop through subdirectories and write to file

I have no idea I have spent a lot of hours dealing with this problem. I need to write script. Script should loop recursively through subdirectories in current directory. It should check files count in each directory. If file count is greater than 10 it should write all names of these file in file named "BigList" otherwise it should write in file "ShortList". This should look like
---<directory name>
<filename>
<filename>
<filename>
<filename>
....
---<directory name>
<filename>
<filename>
<filename>
<filename>
....
My script only works if subdirecotries don't include subdirectories in turn.
I am confused about this. Because it doesn't work as I expect. It will take less than 5 minutes to write this on any programming language for my.
Please help to solve this problem , because I have no idea how to do this.
Here is my script
#!/bin/bash
parent_dir=""
if [ -d "$1" ]; then
path=$1;
else
path=$(pwd)
fi
parent_dir=$path
loop_folder_recurse() {
local files_list=""
local cnt=0
for i in "$1"/*;do
if [ -d "$i" ];then
echo "dir: $i"
parent_dir=$i
echo before recursion
loop_folder_recurse "$i"
echo after recursion
if [ $cnt -ge 10 ]; then
echo -e "---"$parent_dir >> BigList
echo -e $file_list >> BigList
else
echo -e "---"$parent_dir >> ShortList
echo -e $file_list >> ShortList
fi
elif [ -f "$i" ]; then
echo file $i
if [ $cur_fol != $main_pwd ]; then
file_list+=$i'\n'
cnt=$((cnt + 1))
fi
fi
done
}
echo "Base path: $path"
loop_folder_recurse $path
I believe that this does what you want:
find . -type d -exec env d={} bash -c 'out=Shortlist; [ $(ls "$d" | wc -l) -ge 10 ] && out=Biglist; { echo "--$d"; ls "$d"; echo; } >>"$out"' ';'
If we don't want either to count subdirectories to the cut-off or to list them in the output, then use this version:
find . -type d -exec env d={} bash -c 'out=Shortlist; [ $(ls -p "$d" | grep -v "/$" | wc -l) -ge 10 ] && out=Biglist; { echo "--$d"; ls -p "$d"; echo; } | grep -v "/$" >>"$out"' ';'

File comparision using shell script

I have two files named file1 and file2.
Content of file1 --->
Hello/Good/Morning
World/India
Content of file2 --->
Hello/Good/Morning
World/China
I need to check if the contents of these files are equal or not.Since both the files have "Hello/Good/Morning" in common it should print "EQUAL" as per my requirement.I have written a code for this:
file1=/app/webmcore1/Demo/FORLOOP/Kasturi/xyz/pqr.txt
file2=/app/webmcore1/Demo/FORLOOP/Prashast/xyz/pqr.txt
IFS=` `
for i in cat $file1
do
if [ "$i" != '' ]; then
echo "$i"
for j in cat $file2
do
if [ "$j" != '' ]; then
echo "$j"
if [[ $i -eq $j ]]; then
echo "EQUAL"
fi
fi
done
fi
done
But it is not displaying the output properly.
diff compares files, line by line. If diff filename outputs anything, the files are different.
If the output of diff is empty, they are the same.
There already is a tool to compare files, it's called diff (and actually much more powerful than just deciding equal or not, but can be used for this).
diff -q file1 file2 >/dev/null && echo "EQUAL"
If you also want to to print return something in case the files are not equal:
diff -q file1 file2 >/dev/null && echo "EQUAL" || echo "NOT EQUAL"
So, the files are "equal" if they have any single word in common?
result=$(
comm -12 <(tr '[:space:]' '\n' <file1 | sort) <(tr '[:space:]' '\n' <file2 | sort)
)
[[ -n $result ]] && echo EQUAL
Or, just in bash
words=( $(< file1) )
for word in $(< file2); do
if [[ " ${words[*]} " == *" $word "* ]]; then
echo "EQUAL due to $word"
break
fi
done
EQUAL due to Hello/Good/Morning

I'm trying to create a script that'll delete all files which have a bitrate less than 130 kbps

to do that
#!/bin/bash
find ./ -name '*.mp3' | while read -r i; do
echo "----------------------------------------"
if [ $(mp3info -x "$i" | grep Audio | awk '{print $2}') < 130 ]
then
read -p "Delete? " -n 1 -r
if [[ $REPLY =~ ^[Yy]$ ]]
then
rm -f "$i" && echo "$i succesfully deleted!"
fi
fi
echo "----------------------------------------"
done
it stops with this output:
Error opening MP3: /Like A Prayer/Madonna - Act Of Contrition.mp3: No such file or directory
It looks like there is an error with the filepath, cause the leading dot is missing.
I think IFS is set to a value with ".".
Also, to compare integers, use [[ ]]:
#!/bin/bash
find ./ -name '*.mp3' | while IFS='' read -r i; do
echo "----------------------------------------"
if [[ $(mp3info -x "$i" | grep Audio | awk '{print $2}') -lt 130 ]]; then
read -p "Delete? " -n 1 -r
if [[ $REPLY =~ ^[Yy]$ ]]; then
rm -f "$i" && echo "$i succesfully deleted!"
fi
fi
echo "----------------------------------------"
done
Btw I think you have to add your file to the question:
read -p "Delete $i? " -n 1 -r
