Hello,
I need to grep/read files from multiple directories, one by one.
I mean something like shuffling the cards uniformly.
Directory A Includes: (Lets say totally 100 files)
Directory B Includes: (Lets say totally 30files)
Directory C Includes: (Let's say totally 901 files)
In first for loop 1.txt should be read from directory A
1st loop -> directory A, file 1.txt
2nd loop ->directory B, file a.txt
3rd loop -> directory C, file 101.txt
4th loop -> directory A, file 2.txt
If all files in a certain folder had already been read in previous loop, skip that folder...
I'd appreciate if you could explain how I can do that. for is causing problem. Other solutions are also welcome.
Many thanks
Boris

I want a bit of shell script that will let me loop round all the sub-directories in a directory (i.e. ignoring any ordinary files in that directory). Let's say I just want to echo the names of the sub-directories. This sounds like it should be pretty easy - but not for me, it isn't!

paste
paste(1) User Commands paste(1)NAME
paste - merge corresponding or subsequent lines of files
SYNOPSIS
paste [-s] [-d list] file...
DESCRIPTION
The paste utility will concatenate the corresponding lines of the given input files, and write the resulting lines to standard output.
The default operation of paste will concatenate the corresponding lines of the input files. The NEWLINE character of every line except the
line from the last input file will be replaced with a TAB character.
If an EOF (end-of-file) condition is detected on one or more input files, but not all input files, paste will behave as though empty lines
were read from the files on which EOF was detected, unless the -s option is specified.
OPTIONS
The following options are supported:
-d list Unless a backslash character () appears in list, each character in list is an element specifying a delimiter character. If a
backslash character appears in list, the backslash character and one or more characters following it are an element specifying a
delimiter character as described below. These elements specify one or more delimiters to use, instead of the default TAB charac-
ter, to replace the NEWLINE character of the input lines. The elements in list are used circularly. That is, when the list is
exhausted, the first element from the list is reused.
When the -s option is specified:
o The last newline character in a file will not be modified.
o The delimiter will be reset to the first element of list after each file operand is processed.
When the option is not specified:
o The NEWLINE characters in the file specified by the last file will not be modified.
o The delimiter will be reset to the first element of list each time a line is processed from each file.
If a backslash character appears in list, it and the character following it will be used to represent the following delimiter
characters:
Newline character.
Tab character.
\ Backslash character.
Empty string (not a null character). If is immediately followed by the character x, the character X, or any character
defined by the LC_CTYPE digit keyword, the results are unspecified.
If any other characters follow the backslash, the results are unspecified.
-s Concatenate all of the lines of each separate input file in command line order. The NEWLINE character of every line except the
last line in each input file will be replaced with the TAB character, unless otherwise specified by the -d option.
OPERANDS
The following operand is supported:
file A path name of an input file. If - is specified for one or more of the files, the standard input will be used. The standard input
will be read one line at a time, circularly, for each instance of -. Implementations support pasting of at least 12 file operands.
USAGE
See largefile(5) for the description of the behavior of paste when encountering files greater than or equal to 2 Gbyte ( 2**31 bytes).
EXAMPLES
Example 1: Listing a directory in one column
example% ls | paste -d" " -
Example 2: Listing a directory in four columns
example% ls | paste - - - -
Example 3: Combining pairs of lines from a file into single lines
example% paste -s -d" t n" file
ENVIRONMENT VARIABLES
See environ(5) for descriptions of the following environment variables that affect the execution of paste: LANG, LC_ALL, LC_CTYPE, LC_MES-
SAGES, and NLSPATH.
EXIT STATUS
The following exit values are returned:
0 Successful completion.
>0 An error occurred.
