BASH Regex - get filename tags, labels and descriptions
Hi, I am trying to switch from windows to linux.
I have been using Autohotkey scripts for some little things.
I started writing some bash scripts for NEMO browser in linux mint and I am trying to convert some of AHK scripts but as I am not a programmer. I have a hard time with regex stuff.

What I did is split file path and I got it working ok. -- Directory, FileName, Filename-Without-Extension, Extension

Now every filename may or may not contain [tags], {labels} and (description) in brackets at the end of the filename.
Where I am stuck is regex that works in Autohotkey is not in BASH. I tried sed, awk, but I have no idea what I am doing.

example filename:
multiple.{1}(1)[1] dots.and spaces {labels}(description)[tag1 tag2].txt
filename with only tags [tag1 tag2 tag3].txt

Note:
Tags, labels or description can be any words or numbers, not just what I have in example.
Not every filename will have all 3. Some could have only tags, others only descriptions or labels.

need to split and get this:
shortName = "multiple.{1}(1)[1] dots.and spaces" -- filename without any tags,labels and descriptions
tags = "tag1 tag2" -- tags without brackets
labels = "label" -- labels without brackets
description = "description" -- description without brackets


Original regex from Autohotkey that works in all of my scripts

Code:
; NameNoExt is filename without extension
; get filename only without tags[], labels{} or description() 
ShortName:=RegExReplace(NameNoExt, "\s*(\([^()]+\)|{[}]+|\[[^][]+\])+$")
; Get tags
Tags:=RegExReplace(NameNoExt, ".*\[(.*)?\](?!\s).*$", "$1")
; Get labels
Label:= RegExReplace(NameNoExt, ".*\{(.*)?\}(?!\s).*$", "$1")
; Get description
Description := RegExReplace(NameNoExt, ".*\((.*)?\)(?!\s).*$", "$1")



Here is what I have in BASH .. and it is going nowere..
So to mention again, this is where I need help with regex splitting these tags, labels and descriptions.

Code:
str="multiple.{1}(1)[1] dots.and spaces {lab}(desc)[tag1 tag2].txt"

IFS='
'

NameNoExt=`echo "${str%.*}"`        # for filename with multiple dots

shortName="???"        # get "multiple.{1}(1)[1] dots"

#regexp=".*\[(.*)?\](?!\s).*$"    # from autohotkey
regexp="\[([^)]+)\]+$"
if [[ $NameNoExt =~ $regexp ]]
then 
  TAG="${BASH_REMATCH[1]}"
else 
  TAG="Nothing"
fi
#regexp=".*\{(.*)?\}(?!\s).*$"    # from autohotkey
regexp="\{([^}]+)\}+$"
if [[ $NameNoExt =~ $regexp ]]
then 
  LAB="${BASH_REMATCH[1]}"
else 
  LAB="Nothing"
fi
#regexp=".*\((.*)?\)(?!\s).*$"    # from autohotkey
regexp="\(([^)]+)\)+$"
if [[ $NameNoExt =~ $regexp ]]
then 
  DESC="${BASH_REMATCH[1]}"
else 
  DESC="Nothing"
fi
zenity --info --text "`printf "Input = \"$str\"\n\nNameNoExt = \"$NameNoExt\"\nShort Name  = \"$shortName\"\nTags  = \"$TAG\"\nLabels  = \"$LAB\"\nDescription  = \"$DESC\""`"

I highly appreciate any help with this.
Thank you all.
