Why not just use ls -a

Hi Scott!

I realize you first mentioned that in #8. I had been typing up #11 while you submitted that. The sleep was introduced by someone else in #2 where they were attempting to use a ps and...

The "wait" will halt script execution until the program completes. Just placing it in the background via the "&" will allow the script to continue. The bash "$!" environemt variable will return the...

The program may execute much quicker than 2 minutes. Also, I see he's using the bash shell.

Try the following:


./program &
pid=$!


This will run the program in the background and then...

A couple very common examples of hard links being used in an O/S which is not specific to any version:

. is a hard link to the current directory.
.. is a hard link to the parent directory.

Use ksh:

$ foo='1218141 1441 1664 122222'
$ echo $foo
1218141 1441 1664 122222
$ echo $foo | read a b c d
$ echo $a
1218141
$ echo $b
1441
$ echo $c

$ echo $d
122222

Is this what you're looking for?

[rick@kangaroo ~]$ cat kshtest.ksh
#!/bin/ksh

export $1=$2

eval echo $1 = $(echo \$$1)

I'm not 100% clear on what you're attempting, but I did get the "divide by .1" (which is mathematically the same as multiply by 10) part.

Is this close to what you need?

[rick@kangaroo ~]$ cat...

Just ensure that your path is correct.

Instead of


find /path/to/traveldata/data . . .


you should use something like


find ~inbounddata/data . . .


Maybe someone else can...

What O/S & Shell are you working on?

Can you post a complete trace of what you're doing, similar to what I did in my previous reply?

Try adding the -depth option:

[rick data]$ pwd
/path/to/traveldata/data
[rick data]$ ll
total 12
drwxrwxr-x 2 rick rick 4096 2009-03-11 08:00 2009-03-09
drwxrwxr-x 2 rick rick 4096 2009-03-11...

The find is also finding the data folder. You may try something like:


find /path/to/data -type d ! -name data -ctime 0 -exec /bin/rm -Rf "{}" \;

CFAJ's given the best response, but as an exercise here's the answer to the question as you posed it:


[rick@kangaroo ~]$ cat test.sh
#!/bin/bash

testResponseA=3
testResponseB=...

[rick@kangaroo ~]$ a=1.3
[rick@kangaroo ~]$ b=5.1
[rick@kangaroo ~]$ c=$(echo $a + $b | bc)
[rick@kangaroo ~]$ echo $c
6.4
[rick@kangaroo ~]$

Do you need it to be awk/sed?

[rick@kangaroo ~]$ cat test.dat

How about going without the grep? Is there a specific reason it's needed?

You are using DOS directory sep "\" instead of UNIX directory sep "/".

I'd probably go with:


mv $1/$2 Current/

Oops -- didn't read the question well enough before answering. I'll try again.

Second try:

find . -name backuptime.txt -mtime +7 -prune

if that returns nothing, you've done a backup within...

$ cat current.uid user.uid | sort -n | uniq -u
