Scripting mental block

mijohnst · 07-26-2011, 09:29 AM

I'm having a retard moment and I can't figure this out. I have a list of files listed in a error.txt file that I'm trying to copy in a tiny script, but it's doing something and I can't figure out why!

I can echo the file listed:

Code:

[root@testmachine1 rpm_repo]# cat ../error2.txt | awk '{print "echo The filename is "$1}' | bash
The filename is NetworkManager-0.7.0-10.el5_5.2.x86_64.rpm

What doesn't work is when I try and move that file. That file is exactly where the file is showing it, but I keep getting an error saying it ISN'T there.

Code:

[root@testmachine1 rpm_repo]# cat ../error2.txt | awk '{print "ls ../yum/rhel/5/base/"$1}' | bash
: No such file or directoryorkManager-0.7.0-10.el5_5.2.x86_64.rpm

I know it's something simple but I just can't see it. What am I doing wrong? My paths are right, the file is there...my command isn't being interrupted correctly for some reason.

I suspect a special character in your original file. Notice your output doesn't list the name of the file you expect but rather:

Quote:

No such file or directoryorkManager-0.7.0-10.el5_5.2.x86_64.rpm

Try running a "cat -v" on the original file and see if there is a backspace (^H) or something else showing up in the file.

Also you don't have to cat and pipe to awk - you can run your awk on the file itself:

Code:

awk '{print "echo The filename is "$1}' ../error2.txt | bash

By the way - what are you trying to do piping it to bash? An rpm isn't an executable but rather a package so you'd need to operate on the file using the rpm command.

The output looks like there is a carriage return involved.
@OP: Are you trying to edit windows files under linux? If so try running

Code:

sed -i.org 's/\r$//' filename
# or
dos2linux filename

before you execute your script.

A carriage return would show up a ^M.

Running "file ../errortxt2" might be worthwile to see what kind of file it thinks it is.

That was it!! I knew it was something simple... I'm such a dork!

Also, thanks for the info on awk... I'm a creature of habit and since that's the first way I learned it, I type it out without thinking.
