If I want to share a directory called /home/me, would I go to my /etc/exports file and share /home/me/* or would I share /home/me ? I am unsure of how to type this into the file.

Some may recall I recently gave up on bash, rather than give up my programming style.Surely I will have reason to return but that's another story. My little issue now:I am debugging a new [Korn] shell script. I have a function that performs a specialized match on a string and I see that I am able to call that function with no problem, with both of it parameters. The function does not do any print or echo command - it uses "return" for a TRUE (0) of FALSE (1), as is the shell exit code convention. Thus, I have the following test:
Code:
if [[ match_except_release ${PATH_DIR[$LC]} bin ]]

I am trying to modify a script for research purposes and am having difficulty here as I have little prior experience with C-shell scripting.
The script looks as follows (it includes tcl commands like runFEP that you can ignore)
#!/bin/bash
for ((old=1, new=2; old<=4; old++,new++))
a1=${old}%50
a2=${new}%50
do
cat > input${new}.conf <<EOF
${a1}
code....
My question: I keep getting a syntax error when defining my two variables a1 and a2. I essentially need these variables to be
a1 = value of variable old divided by 50
a2 = value of variable new divided by 50
Im a bit stuck with a simple script that im practicing with... im trying to get my head around some simple scripting. Basically i want to write a script that will work as below: It will ask the user to enter their userid. If its correct it will say 'Correct' If its the wrong id (But the ID exists in /etc/passwd) then it will say 'incorrect' If its not a valid userid it will say 'doesnt exist'. What i have so far is:
[Code]...
# If the user enters their own userid they will get a comment saying 'correct' $LOGNAME) echo "Correct";;
# If they enter another users ID (That exists in the /etc/passwd), then they get a message to say 'incorrect userid used'. Im not sure what i need to do here to get it to check the /etc/passwd to see if the input exists in there.... im guessing some kind of simple 'if' statement to say ---- "if 'input' exists in /etc/passwd then echo "incorrect userid used"
# If its entered incorrectly and not a valid ID then they will get this comment. Again, im guessing this part would be similar to te above option..... *) echo "not a valid ID";;
Ive managed to work out how the basic Case staements work, but to add a conditional statement based on the input, i just cant figure out. I have tried looking on google, and found some help but it doesnt really explain how i check the input against the /etc/passwd.

I want to rename some files in one directory and found the command 'rename' most appropriate.
Changing the file extension is easy since there are lot of examples for this.
But now I want to rename my files like this:
'somePrefix_blablabla.ext' --> '0_blablabla.ext'
'somePrefix_blablablablabla.ext' --> '0_blablablablabla.ext'
I DON'T want an incrementation, just the leading prefix '0_'
correct perl expression syntax for this?
When ever i open vim, i get the error that the following error: E484: Can't open file/abcd/configFiles/vim/syntax/syntax.vim There was a .vimrc file in my home folder that i have removed.
Still i keep getting the same error. Presently in my home folder there is no .gvimrc or .vimrc file.

I am a Novell (now defunct) CNE tring to learn Linux and am having a lot of trouble finding out where the WB 6-6 is wrong in the syntax for adding local4... the the syslog-ng config file. In the instructions there are discrepancies between commas and simi-comma, they are both in the statements in no particular order. there is no pattern to them. Here is what the book shows:
filter f_local4debug { level(debug) and facility(local4); };
When I try to input this in the Gnome terminal window to try and find out where it goes wrong I get the following: -bash: syntax error near unexpected token "(" If I can get the correct syntax I belive I can use the info to get past the rest of this portion of the lesson. I am desperate to learn Linux as the only jobs out there for a Novell CNE are migrations to MS, which really sucks, since MS really really sucks.
I'm trying to craft a tricky regex using Sed. I'm trying to clean up some code which has bazillions of lines over 80 characters in length, mainly because of these end-of-line comments. I want to change them to a nicer format. I've put the code on Pastebin because the formatting is better: [URL]. Bear in mind those are tabs, not spaces.

My friend lost her dissertation and she had only a pdf copy of it. I am trying to convert the pdf into an odt format. After copy-pasting the content into an odt, i need to replace all paragraph breaks which are not following a dot with a space. For which i thought of using the regular expression feature of Libre Office. I've not succeeded so far.
I tried: to replace [:alpha:]$ or [a-z]$ or [a-z]>$ with space, but none of them worked. Finding [a-z] seems to work, finding [a-z]> too. So did finding $ (end of paragraph) but if i combine any regex with $ then it doesn't find anything.

So I just recently downloaded Regex-PreSuf. I believe it downloaded correctly, and also install correctly (did the following):

The output from the make, and make install gave the All OK, but there is no documentation with it that shows how to use it? Does anyone know what you have to do to use it? From what I read, it is used to enter a string and it gives you the regex that matches that string exactly? This is what I tried, from within the directory and its the output:
