How to automatically date the input directories

Hi folks,

How to automatically date the input directories

I have following script with preset directories which can be dated automatically when they are copied for burning

Script:-

Code:

#!/bin/bash
set -x

#Set directory path...
user=$(whoami)
now=$(date +%Y.%m.%d.%R)
ISO_File="/tmp/satimis/image_${user}_${now}.iso"

# Temporary file to store the resulting mkisofs command
CmdFile_1=/tmp/satimis/.TmpBurnCD$$
list=""

CopyDir(){
name=$1
dir=$2

if [ "$Default" = "" ];then
list="$list \"$name=$dir\""
else
if [ "$Default" = "yes" ];then
list="$list \"$name=$dir\""
fi
fi
}

# Preset directories for copying...
B123() {
CopyDir "/B123_${now}/" "/pathto/B123"
}

C123() {
CopyDir "/C123_${now}/" "/pathto/C123/"
}

D123() {
CopyDir "/D123_${now}/" "/pathto/D123/"

# Choosing preset directores for copying
REPLY="B"
until [ -z "$REPLY" ]

do
echo "Choose any of the following:"
echo
echo "[B]123"
echo "[C]123"
echo "[D]123"
echo "[A]ll
echo
echo "[Enter] = Exit"
echo

read

case "$REPLY" in

# Accept upper or lowercase input...
"B" | "b" )
B123
;;

"C" | "c" )
C123
;;

"D" | "d" )
D123
;;

"A" | "a" )
B123
C123
D123
;;

* )
#Default option.
# Do nothing for other keys
;;

esac
done

# Loop to get other directories...
echo "Enter directories to burn. Leave blank to end list"
entry="empty"

until [ -z $entry ]; do
echo -n "Enter a directory (eg: /ABC/=/pathto/ABC): "
read entry
if [ "$entry" != "" ]; then
list="$list \"$entry\""
fi
done

# If at least one directory has been entered....
if [ "$list" != "" ];then
#Construct the mkisofs command...
echo "/usr/bin/mkisofs -R -l -o $ISO_File -hide-rr-moved -graft-points \
$list" > "$CmdFile_1"
.......
.....

Now my problem is unable to automatically date additional directories input. I tried many variation on;

if [ "$entry" != "" ]; then
and

list="$list \"$entry\""
without result, such as;

"$entry" != "_${now}"
"$entry" "!_${now}"= ""
"$entry" != ""_${now}
list="$list \"$entry\_${now}\""
list="$list \"$entry${now}\""
etc.

Since the pattern of input is "/ABC/=/pathto/ABC" I'm not allowed to separate it.

Any advice. TIA

Try this:

Code:

until [ -z $entry ]; do
echo -n "Enter a directory (eg: /ABC/=/pathto/ABC): "
read entry
if [ "$entry" != "" ]; then
  ### FOR DATE PADDING
  dt_path=$(echo $entry |awk -F"=" '{print $2}')
  point=$(echo $entry |awk -F"=" '{print $1}' |awk -F"/" '{print $2}')
  point=$(echo "/${point}_${now}/")
  entry=$(echo "/${point}/=${dt_path}"
list="$list \"$entry\""
fi
done

You can also use "cut" instead of "awk" but I think awk eliminates problems even if the user input for "entry" contains spaces.

HTH.

Replace,

Code:

entry=$(echo "/${point}/=${dt_path}"

With this:

Code:

entry=$(echo "/${point}/=${dt_path}")

Forgot the closing parenthesis.

HTH.

Tks for your advice on 2 postings which worked for me seamlessly. I never imagin so complicate.

Could your please help me to understand those lines.

1. dt_path=$(echo $entry |awk -F"=" '{print $2}')
2. point=$(echo $entry |awk -F"=" '{print $1}' |awk -F"/" '{print $2}')
3. point=$(echo "/${point}_${now}/")
4. entry=$(echo "/${point}/=${dt_path}")

Suppose entry is "/ABC/=/pathto/ABC"

Here we split this value into two parts, append the date to the first part & put them back together.

1. Save "/pathto/ABC"
2. Extract "ABC" from "${entry}"
3. Append "_${now}" to "ABC"
4. Put the "ABC_${now}" & "/pathto/ABC" back together.

HTH.

Tks for your explanation.

"awk" is a handy tool which is new to me. Google search brought me many links;

Could you please recommend me an awk documentation to read. TIA
