script for zipping files

[DanglingChap]

Hi,

I have few files that are being generated randomly. there names are

• File 1
• File 2
• File 3
• File 4
• File 5
• File 6

I want to write some script, which get all the files from the directory with such name formate and make zip file (1 zip for each file) and the name of the zip file should be like

file - <date on which it was created>.tar.gz

I have good knowledge of programming. but i dun have any idea to write script on linux. so instead of going through all that basic stuff, i want to focus on this particular problem - so that i may finish it earlier.

How about this:

tar -cvzf `date +"%Y%m%d"`.tar.gz /path/to/File\ *

How about this:

tar -cvzf `date +"%Y%m%d"`.tar.gz /path/to/File\ *

thanks. but i guess this will make the tar file with *current date time*. i want to make the tar file with the date at which the original file (file1) was created.

see, the file1 may have been created on a week ago and i am gona make the tar file a week later. so i want the tar file name appended with date/time at which the file was created i.e. week ago.

You could try something like date = `ls -l|awk '{print $6}'`, then use $date as part of your filename.

for file in "File *"; do zip "$file" "${file}-${date}.zip"; done

You need to extract the creation date as someone told you above.

Sorry, how about this:

#!/bin/bash

find /path/to/File\ * | while read FLE
    do
        DATE=$(ls -l --time-style=+%Y%m%d "$FLE" | awk '{print $6}')
        BASE="`basename \"$FLE\"`"
        tar -cvzf "${BASE}-${DATE}.tar.gz" "$FLE"
    done

        BASE="`basename \"$FLE\"`"
        tar -cvzf "${BASE}-${DATE}.tar.gz" "$FLE"
    done

emm, that sounds cool. now the only question.

i save the script in which file? what should be the file extension and how'd i execute it ?

sorry, quite basic question but i don't know.

File extensions don't matter that much in the Unix/Linux world. You can just put it in a text file and save it any way you like though often people append the .sh extension. With regards to executing it there are two ways

• Use sh to call it
• Amend the permissions to add executable and then put it somewhere in your $PATH

To check what your $PATH is just run

echo $PATH

You can add execution permission by running this, or within the properties dialogue.

chmod +x filename.sh

The thing I forgot to mention is that if you're going to compress each file into its own compressed file then there's no need to use tar. You can either use gzip or zip directly as follows:

gzip < "$FLE" > "${BASE}-${DATE}.gz"

zip "${BASE}-${DATE}.zip" "$FLE"

i wrote this code ..

#!/bin/bash

find /server-logs/catalina.out.\ * | while read FLE
    do
        DATE=$(ls -l --time-style=+%Y%m%d "$FLE" | awk '{print $6}')
        BASE="`basename \"$FLE\"`"
		zip "${BASE}-${DATE}.zip" "$FLE"
    done

change the mode to executable/writable .. and when i entered this command

sh zipping-script.sh

it threw following errors

: command not foundline 2: 
zipping-script.sh: line 9: syntax error near unexpected token `done'
zipping-script.sh: line 9: `    done'
