[Solved] bash: How to go about creating a script to choose from a list

Gen2ly · 2009-10-13 02:12:09

Tried a Google search on this and didn't get much, if I missed something really obvious please give a link, otherwise I'd really appreciate any help. I'd like to be able to build a script that will check files names for their appended date and allow the user to be able to choose which one of them to restore from a list. Perhaps, it's better if I just put up the script:

...
bacdir=/root/backup/kde4-plasma-rcs
plasmarcs=$(find $HOME/.kde4/share/config -type f -name "plasma*")
date=$(date +%F)

# Check for differences in files, only backup if there are


case $1 in
  r | restore ) echo "Choose the plasma configuration you'd like to restore"
                read selection
                if [[ $selection ==
                ;;
  * )           for rc in "$plasmarcs"; do
                  cp "$rc" "$bacdir"/"$rc"-"$date"
                done
                ;;
esac

And that's as far as I've gotten. I thought about doing something like `ls ${backdir##*-}` then finding a way to put that in a list not sure how to do that. Are there better ways to do this, then allow an action to be takenafterword.

Since you already found the list with find, maybe something like this would do.

for rc in $plasmarcs; do echo $rc; done

edit: fixed wrong var name

Apart from zenity and dmenu, I'd use something like this:

IFS='
'
plasmarcs=($(find "$backdir" -type f -name "plasma*")) # put results in an array
unset IFS
for((i=0;i<${#plasmarcs[@]};i++)) ; do
    echo "${i}) ${plasmarcs[$i]}"
done
echo -n "Choose the plasma... "
read n
selection="${plasmarcs[$n]}"
echo "$selection" # do something else

This is what I used in my apple trailer script too.
you can also use `ls -1 "$backdir"/*` instead of find if backups are all in one dir.

Not sure why I didn't think of the trailer script before... . Good news though is that I did get it done. Not quite sure how the i=0;i<:i++ works just yet but got the thought. Here's the script for anyone interested:

#!/bin/bash
# plasmabak - backup and restore local plasma config

# text color variables
bldylw='\e[1;33m' # yellow
bldblu='\e[1;34m' # blue
bldwht='\e[1;37m' # white
txtrst='\e[0m'    # text reset

backdir=/root/backup/kde4-plasma-rcs
userdir=/home/todd
plasmarcs=($(find "$userdir"/.kde4/share/config -type f -name "plasma*"))
bkpplasmarcs=($(find "$backdir" -type f -name "plasma*"))
date=$(date +%F)

# Display usage if full argument isn't given
if [[ -z "$@" ]]; then
  echo " ${0##*/} b|r - backup or restore plasma configurations"
  exit
fi

# Create backup directory if it doesn't exist
if [[ ! -d "$backdir" ]]; then
  mkdir "$backdir"
  echo "${bldblu}*${txtrst} KDE 4 plasma config backup directory doesn't exist.  Created."
fi

# Delete backups older than two months
if [[ -n "$(find "$backdir" -mtime +60)" ]]; then
  find "$backdir" -mtime +60 -exec rm {} \;
  echo "${bldblu}*${txtrst} Configurations older than two months deleted"
fi

case $1 in
  b | backup )  tar -czvpf "$backdir"/plasmarcs-"$date".tar.gz ${plasmarcs[@]}
                ;;
  r | restore ) for((i=0;i<${#bkpplasmarcs[@]};i++)) ; do
                  echo -e " ${bldwht}${i}) ${bkpplasmarcs[$i]##*/}${txtrst}"
                done
                echo -n "Choose the plasma configuration to restore: "
                read restore
                selection="${bkpplasmarcs[$restore]}"
                tar -xvf "$selection" -C /
                echo -e " ${bldwht}*${txtrst} Restored plasma configs: ${bldwht}${bkpplasmarcs[$restore]##*/}${txtrst}"
                ;;
  * )           echo -e " ${bldwht}*${txtrst} Use 'plasmabak b' to backup and 'plasmabak r' to restore"
esac

Appreciate the help, lolilolicon.
