Operating Systems OS X (Apple) Remove leading spaces from file names and folders Post 302801787 by prometheon123 on Thursday 2nd of May 2013 02:16:50 PM

Remove leading spaces from file names and folders

Hi All,

I have a vexing issue with leading spaces in file names. Basically, we're moving tons of data from our ancient afp file share to Box.com and Box forbids leading spaces in files or folders. The HFS file system seems to be perfectly fine with this, but almost all other Unix file systems are not. Of course, our users put leading spaces in some of their file names and folders so that those files and folders would show up at the top of the directory listing in the Finder. I have almost seven thousand of these instances spread out among 600 gigs of file data. My bash script already strips out illegal characters, however, I'm not sure how to add leading spaces to the script. Any advice would be greatly appreciated.

Code:
#!/bin/bash

# Find all files or folders containing 'bad' characters.
find . -depth -name "*[^a-zA-Z0-9._- ]*" |
# Read them line-by-line.
while read FILEDIR
do
       # Get the folder its inside
       DIR="${FILEDIR%/*}"
       # Get the plain name.
       FILE="${FILEDIR/*\/}"
       # Substitute _ for bad things.
       NEWFILE="${FILE//[^a-zA-Z0-9._- ]/_}"
       # Rename it.
       mv "$DIR/$FILE" "$DIR/$NEWFILE"
done

folders(1)						      General Commands Manual							folders(1)

NAME
folders - list folders and contents (only available within the message handling system, mh) SYNOPSIS
folders [+folder] [msg] [options] OPTIONS
Lists only the name of folders, with no additional information. This is faster because the folders need not be read. Prints a list of the valid options to this command. Lists the contents of the folder-stack. No +folder argument is allowed with this option. Re-numbers mes- sages in the folders. Messages are re-numbered sequentially, and any gaps in the numbering are removed. The default operation is -nopack, which does not change the numbering in the folder. Discards the top of the folder-stack, after setting the current folder to that value. No +folder argument is allowed with this option. This corresponds to the popd operation in the C-shell; see csh(1). The -push and -pop options are mutually exclusive: the last occurrence of either one overrides any previous occurrence of the other. Pushes the current folder onto the folder-stack, and makes the +folder argument into the current folder. If +folder is not given, the current folder and the top of the folder-stack are exchanged. This corresponds to the pushd operation in the C-shell; see csh(1). The -push switch and the -pop switch are mutually exclusive: the last occurrence of either one overrides any previous occurrence of the other. Lists folders recur- sively. Information on each folder is displayed, followed by information on any sub-folders which it contains. Displays only the total number of messages and folders in your Mail directory. This option does not print any information about individual folders. It can be sup- pressed using the -nototal option. The defaults for folders are: +folder defaults to all msg defaults to none -nofast -noheader -nototal -nopack -norecurse DESCRIPTION
The folders command displays the names of your folders and the number of messages that they each contain. The folders command displays a list of all the folders in your Mail directory. The folders are sorted alphabetically, each on its own line. This is illustrated in the following example: Folder # of messages ( range ); cur msg (other files) V2.3 has 3 messages ( 1- 3). adrian has 20 messages ( 1- 20); cur= 2. brian has 16 messages ( 1- 16). chris has 12 messages ( 1- 12). copylog has 242 messages ( 1- 242); cur= 225. inbox+ has 73 messages ( 1- 127); cur= 127. int has 4 messages ( 1- 4); cur= 2 (others). jack has 17 messages ( 1- 17); cur= 17. TOTAL= 387 messages in 8 folders. The plus sign (+) after inbox indicates that it is the current folder. The information about the int folder includes the term (others). This indicates that the folder int contains files which are not messages. These files may be either sub-folders, or files that do not belong under the MH file naming scheme. The folders command is identical to the effect of using the -all option to the folder command. If you use folders with the +folder argument, it will display all the subfolders within the named folder. as shown in the following exam- ple: % folders +test Folder # of messages ( range ); cur msg (other files) test+ has 18 messages ( 1- 18); (others). test/testone has 1 message ( 1- 1). test/testtwo has no messages. TOTAL= 19 messages in 3 folders. See refile(1) for more details of sub-folders. RESTRICTIONS
MH does not allow you to have more than 100 folders at any level in your Mail directory. PROFILE COMPONENTS
Path: To determine your MH directory Folder-Protect: To set protections when creating a new folder Folder-Stack: To determine the folder stack lsproc: Program to list the contents of a folder FILES
