ShellScript - Rename File Help

dwnewyork5dwnewyork5 Member
in General

Can someone help me write a bash/ shell script command to rename a cPanel Backup file to a new name? There are around 10 different files in a folder which needs to be renamed.

Original: backup-8.24.2016_17-39-13_.tar.gz
New: _temp_YYYYMMDD.tar.gz
YYYYMMDD needs to come from the original file name.

Thanks in advance.

    It's been a while since I've restored a cPanel backup, but if memory serves... doesn't it freak out if your backup file isn't named in just the right way? You'd hate to have to rename them when you wanted to use them.

    Show us your start on the problem and we'll help.

    Are you sure this isn't "can someone write a script for me that I can copy/paste"...

    Just 10? This doesn't need a script for that imho.

    Will be honest. I have 0 clue with shell scripting . I need to rename files in a multiple folders before I archive them to ACD. Just don't wanna get flagged if using a standard name. Hence the help request.

    find . -type f -name "backup*" -print0 | while read -r -d '' file; do

    mv "$file" "${file//backup/TEST}"

    done

    Will find all files that start with backup recursive and then change the text in the filename from backup to TEST

    This exactly

    Then go php do.php (assuming do.php is the file with that code). Sure it's not bash but it IS technically a shell script when you run it from the CLI.

    Code is untested, written at the verge of getting drunk. Use at your own risk.

    Bringing PHP to an awk/sed party generally ensures drunkenness somewhere. ;)

    I'd start with djn's script, and just abuse cut on the filename to make it fit your request:
    cut -f1 -d_ | cut -f2 -d-

    I wouldn't do that on the fly but rather in vi (or whatever good editor you have) after piping the "ls backup-*" into some temp file.
    The tricky part is that you also want to flip the date order to yyyymmdd. That's easy with a regex.
    But there is another problem in that you don't want date item separators, which means you'd need to write some script to 0-fill the year, month, and day to 4 or 2 digits. As I assume that not having element separators isn't really important for you I suggest the following (example in vi):

    s:backup-\(\d\+\)\.\(\d\+\)\.\(\d\+\)_\(.\+\)\.tar\.gz:mv backup-\1.\2.\3_\4\.tar\.gz temp\3_\2_\1\.tar\.gz:g

    You may, of course also use sed or whatever but you should be aware of subtle differences in regex syntax.

    Once you are done you can save the file that now consists of lines like
    'mv backup-8.24.2016_17-39-13_.tar.gz _temp_2016_8_24.tar.gz'
    and run it through bash to actually rename your files as desired.

    P.S. Forgive my poor formatting. I don't know how to nicely format stuff here.
    P.P.S. That was a pain in the ass with this blog software. Unless someone tells me how to verbatim "code" format something this was the last time I helped with code here.

    Yep. I was so used to batch-renaming my linux ISOs this way, couldn't help it.

    I'm guilty of doing the same if it's faster (and throwaway).

    happy new year

    • shell script http://pastebin.com/v5D1Hejk and set BACKUPDIR variable to path to your backup directory containing backup-* tarballs
    • defaults to DEBUG=y which when run only echos old and new file names without actual renaming to doublecheck it's what you want
    • then for live run edit DEBUG=n and re-run script

    example DEBUG=y output

    ./convert.sh                        
found backup-8.24.2016_17-39-13_.tar.gz
-------------------------------
debug mode output: 
_temp_2016824
17-39-13
.tar.gz
-------------------------------

renaming backup-8.24.2016_17-39-13_.tar.gz to _temp_2016824.tar.gz ...
-------------------------------
debug mode output (echo only): 
original file: /path/to/cpanel/backupdirectory/backup-8.24.2016_17-39-13_.tar.gz
renamed file: /path/to/cpanel/backupdirectory/_temp_2016824.tar.gz

    example DEBUG=n output

    ./convert.sh                        
found backup-8.24.2016_17-39-13_.tar.gz
renaming backup-8.24.2016_17-39-13_.tar.gz to _temp_2016824.tar.gz ...
mv /path/to/cpanel/backupdirectory/backup-8.24.2016_17-39-13_.tar.gz /path/to/cpanel/backupdirectory/_temp_2016824.tar.gz
  • bsdguybsdguy Member

    Nice. Note, however, this -> "to _temp_2016824.tar.gz"

    What if the month was jan or feb? say 24.1.2016 ... then the result would be _temp_2016124.tar.gz ... which could mean dec. 4 or jan 24.

    That's why I included element separators to have a result like _temp_2016_1_24.tar.gz. If he/she doesn't like that one needed to 0-fill the elements.

  • eva2000eva2000 Veteran

    yeah i just used the example @dwnewyork5 posted literally heh

  • eva2000eva2000 Veteran

    @bsdguy fixed and updated original pastebin to check for single or double digit months

    with DEBUG=n set

    ./convert.sh    
found backup-1.24.2016_17-39-13_.tar.gz
renaming backup-1.24.2016_17-39-13_.tar.gz to _temp_20160124.tar.gz ...

    'date' is flexible and can do all kinds of formats:

    ls backup-*_.tar.gz | while read orig; do m1=${orig#*-}; m2=${m1%%_*}; m3=${m2//\./\/}; echo mv $orig $(date --date="$m3" "+_temp_%Y%m%d.tar.gz"); done

    If you could guarantee GNU coreutils, it's all simple. However, that isn't always the case. ;) I'd also suggest quotes around the variables in case there is a space or other delimiter that would possibly cause chaos.
