So if the script finds a variable in a line. i want it to output the results to that line . sed -i did not work for me; sed: couldn't open temporary file ./sedTvOCEg: Permission denied

Changing $files to "$files" eliminate these problems but causes that whole content of variable is treated as one string (one execution of loop).

Firstly, i'm NEW to Linux and my very first time with DSL. I'm installing this on an older Dell Latitude laptop.
I just finally got the DSL installed on my HDD successfully and then I added feh to start and run at start up, then I rebooted and now i'm getting this error:
No, directory, logging in with HOME=/ -bash: cd: /home/dsl: Permission denied
I have tried reading numerous websites but none explains to the level whereby I can understand. I even tried rebooting from the CD, but could not figure out how/what to do next?
The question is, can someone explain how I can use the DSL CD to try to correct this error. More importantly, can you explain in layman terms so that I can actually put it good use.
Also, some additional questions I have....when you download a file where does it save to?

I'm trying to make another file annotation script a little speedier than it has been by the up-until-now proven method of checking the last four characters in a filename before the "dot" (eg .jpg, .psd) against a list of known IPTC categories and Exiv2 command files. It occurred to me that if one script generated a list of files in directory foo, and the same or another script sorted that list by that four-letter tag,then that list could be used(instead of a for/do/done loop on the real files in the folder) by the command-file-matching script to "vomit out" which annotator file would go with file nastynewfile.jpg, f'r'instance. The script I had been using for this task looks like this:
Code:
while read 'line';
do
sp=$(echo $line)
vc=$(echo $sp | cut -d"," -f1)
cv=$(echo $sp | cut -d"," -f2)

Where I seem to be stuck is with how to sort the lines in templist, which may be any number of different lengths, from back to front. sort -k looked promising, except it seems only to work the other way round. I thought of invoking a
Code:
q=$(expr length $line); echo $q
n=$[q-8]; echo $n
kind of thing, but that presented the problems of how to sort by those, how to tell sort where to find them (grep?) and how to "stitch them back in" to the original list, which is what I want to sort in the first place.

I've been searching alot on the internet and I know the issue is permission related, but I don't know how to fix it. I've seen some forum posts that say you need to use the chmod 775 command on the /var/www/html folder.Currently when I do ls -l /var/www/html it returns

-rw------- 1 root root 19 May 5 13:15 index.php~
I'm sure that this isn't correct but like I said I don't know much about how to set permissions or who the owner needs to be. I've done alot of searching and seen similar posts, but no one seems to explain it clearly.
