Full Discussion: Copying files with spaces in the filename in a for loop
Top Forums UNIX for Dummies Questions & Answers Copying files with spaces in the filename in a for loop Post 302597447 by Scrutinizer on Friday 10th of February 2012 10:38:35 AM

The trouble is grep -Eo '[0-9]{3,4} wil also match the numbers after the /
This can also be done with plain shell:

Code:
while IFS="-/" read x cam x
do
  while read file
  do 
    case $file in
       *$cam*) cp "$file" cameras
    esac
  done < list3
done < list2

But this reads list3 multiple times. This would be more efficient for example:

Code:
while IFS="-/" read x cam x
do
  cameras="$cameras $cam"
done < list2

while read file
do 
  for cam in $cameras
  do
    case $file in
      *$cam*) cp "$file" cameras
    esac
  done
done < list3

ff

ff(1M)                                                    System Administration Commands                                                    ff(1M)

NAME

       ff - list file names and statistics for a file system

SYNOPSIS

       ff [-F FSType] [-V] [generic_options] [-o specific_options] special...

DESCRIPTION

       ff  prints the pathnames and inode numbers of files in the file system which resides on the special device special. Other information about
       the files may be printed using options described below.  Selection criteria may be used to instruct  ff to only print information for  cer-
       tain  files.  If no selection criteria are specified, information for all files considered will be printed (the default); the -i option may
       be used to limit files to those whose inodes are specified.

       Output is sorted in ascending inode number order.   The default line produced by ff is:

              path-name i-number

       The maximum information the command will provide is:

              path-name i-number size uid

OPTIONS

       -F                      Specify the  FSType on which to operate. The  FSType should either  be  specified  here  or  be  determinable  from
                               /etc/vfstab by matching the  special with an entry in the table, or by consulting /etc/default/fs.

       -V                      Echo  the complete command line, but do not execute the command. The command line is generated by using the options
                               and arguments provided by the user and adding to them information derived from  /etc/vfstab.  This  option  may  be
                               used to verify and validate the command line.

       generic_options         Options that are supported by most FSType-specific modules of the command.  The following options are available:

                               -I              Do not print the i-node number after each path name.

                               -l              Generate a supplementary list of all path names for multiply-linked files.

                               -p prefix       The specified prefix will be added to each generated path name. The default is `.' (dot).

                               -s              Print the file size, in bytes, after each path name.

                               -u              Print the owner's login name after each path name.

                               -a -n           Select if the file has been accessed in n days.

                               -m -n           Select if the file has been written or created in n days.

                               -c -n           Select if file's status has been changed in n days.

                               -n file         Select if the file has been modified more recently than the argument file.

                               -i i-node-list  Generate  names  for  only those i-nodes specified in i-node-list. i-node-list is a list of numbers
                                               separated by commas (with no intervening spaces).

       -o                      Specify  FSType-specific options in a comma separated (without spaces) list  of  suboptions  and  keyword-attribute
                               pairs for interpretation by the FSType-specific module of the command.

OPERANDS

       special         A special device.

       /etc/vfstab             list of default parameters for each file system

ATTRIBUTES

       See attributes(5) for descriptions of the following attributes:

       +-----------------------------+-----------------------------+
       |      ATTRIBUTE TYPE         |      ATTRIBUTE VALUE        |

NOTES

       This command may not be supported for all  FSTypes.

       The  -a, -m, and -c flags examine the  st_atime, st_mtime, and st_ctime fields of the stat structure respectively.  (See stat(2).)
