Field (column 1) goes up to 24 in both File 1 and File 2.
File 1 is unsorted.
File 2 is sorted, from 1-24 in column 1. It is then sorted by lowest number number in column 2 (real values are from 1-about 30,000,000).
So this means that if column 1 = 1, values could be from
or
There is no fixed number by which column 2 increases by, nor is there a fixed number by which column 3 increases by. The lowest possible number in column 2, and highest possible number in column 3 changes depending on whether there is 1,2,3,4 etc in column 1.

I've got this problem, if I modify an array in the loop and print it, everything is fine as long as I stay in the loop. But, when I print it outside the loop, nothing happens... How can I solve this problem?

Hi All,
I am trying to run a do while for an array. And in the do while, I'm trying to get a user response. Depending on the the answer, I go ahead and do something or I move on to next element in the array.
So far I can read the array, but I can't get the if statement to work. Any suggestions... (5 Replies)
Below is a test script I was trying to use so that I could understand why the logic was not working in a larger script.

Hi there,
A bit new to bash and am having an issue with a for loop. I look for filenames in a specified directory and pull the date string from each meeting a certain criteria, and then would like to make a directory for each date found, like this:

rbash
RBASH(1) General Commands Manual RBASH(1)NAME
rbash - restricted bash, see bash(1)RESTRICTED SHELL
If bash is started with the name rbash, or the -r option is supplied at invocation, the shell becomes restricted. A restricted shell is
used to set up an environment more controlled than the standard shell. It behaves identically to bash with the exception that the follow-
ing are disallowed or not performed:
o changing directories with cd
o setting or unsetting the values of SHELL, PATH, ENV, or BASH_ENV
o specifying command names containing /
o specifying a file name containing a / as an argument to the . builtin command
o specifying a filename containing a slash as an argument to the -p option to the hash builtin command
o importing function definitions from the shell environment at startup
o parsing the value of SHELLOPTS from the shell environment at startup
o redirecting output using the >, >|, <>, >&, &>, and >> redirection operators
o using the exec builtin command to replace the shell with another command
o adding or deleting builtin commands with the -f and -d options to the enable builtin command
o using the enable builtin command to enable disabled shell builtins
o specifying the -p option to the command builtin command
o turning off restricted mode with set +r or set +o restricted.
These restrictions are enforced after any startup files are read.
When a command that is found to be a shell script is executed, rbash turns off any restrictions in the shell spawned to execute the script.
