I'm writing a script using ksh that diffs two dirs that contain about 30 files, and writing the results on a logfile. When files differ, it writes the difference with no problem, but I also need the script to write a message if no differences are found.
View 3 RepliesI cannot print pdf files. I have tried using okular and xpdf. The documents display in the program, but print preview shows a blank page. The printer then sends out blank pages. I have tried printing on 2 different printers using usb cables. Using terminal to process the commands shows error:

Converting to .ps also is blank.
I need some direction on a small scripting question. I've been doing some development and storing the code on a network drive with multiple user access. My development is getting complex enough that it is time to set up a svn repo for it. I would like to set up a little script (if possible) that prints a message/reminder to whomever is accessing the code directory stating that the code is ultimately stored in svn and any changes need to be checked in, etc. Is there a way to have linux print a message to the screen based on a 'cd /specific_dir/' command? So far google is mum on the topic. Using Debian and bash shell.

I initially had a problem accessing the CUPS interface (see my other post) and got that resolved by adding the user "cupsys". Now, everything "looks" ok, and when I print a test page, it shows it as completed (in CUPS). However, the page never prints.

I would like to compare two md5sum outputs to see if the files match. in my script I have
Code:
ORG_FILE="/path/to/org/file.zip"
NEW_FILE="path/to/new/file.zip"
MD5_ORIG=$(md5sum -b "$ORG_FILE")
[code]....
How do I get just the MD5 hash and not the */.... stuff so I can compare them. i tried Code: JUST_HASH=${$MD5_ORIG:0:32} but All I get is
dir_mon_notify.sh: line 79: ${$MD5_ORIG:0:32}: bad substitution
I have the following query:
Code:
$sql="SELECT table1.datetime, table1.user_id, table2.ip, FROM table1,table2 WHERE id='$id' AND (table1.id = table2.id AND table1.datetime = table2.datetime)";
In table2 the datetime fields are about 1 to 2 seconds off due to the source of the data, which I cannot change.
Is it possible via a query match table1.datetime & table2.datetime by HH:MM (ie. to the minute instead of to the second)?
Our one remaining problem seems to be printing. She has an HP OfficeJet 6500 USB printer. We have the computer conntected. Strangely, when I boot from the CD the printer shows up as installed even though I did nothing to install it. After having submitted a print job it shows the printer status as "idle" and the print queue is empty. I tried deleting that printer and re-installing. The installation went as one would expect. However the results are the same. I'm beginning to think that somehow the problem is related to the fact that we are operating from the live CD. getting this thing to print from the live CD.

I would like to make a one-liner, which diff's "ps aux" output before and after killing a process. So basically it should be a combination of fallowing commands:
1) diff -u
2) ps aux | awk '{print $2}'
3) kill `ps aux | grep [c]ron | awk '{print $2}'`
4) ps aux | awk '{print $2}'
How to achieve this? Something like this:
Code:
diff $( kill `ps aux | grep [c]ron | awk '{print $2}'` && ps aux | awk '{print $2}' ) $( ps aux | awk '{print $2}' )
I don't have pgrep or pkill available.
I'm new to scripting and I have a trouble with if statement syntax. The code is: Code: #there is a diff command here, and it does what i want but#i wanna see 1 if the exit value of diff is 0, and otherwise i wanna see 0.#the problem is here: (syntax error near unexpected token "then")
if["$?"==0];

i tried using diff --GTYPE-group-format= with <%, but not sure that right solution.Here's what im trying to do. I have two c source files, file1 and file2. file1 has a function in it that's been modified in file2. However, the functions begin at differnt line numbers in eachof the files. Is there a way to specify a range of file numbers on file1 and file2 to compare, using diff or any other combination of utilities? I can always output text from a range of lines from each file to two separate and new files and then compare those, but that's tedious. I could also write up a script to automate this type of solution, but I imagine there's an existing way of doing this.

I need to edit the sudo file on lots of machines. I figure the easiest way is to run a for loop to ssh to each box, sed the sudoers file to a new file & copy/move back over the top of the original (and of course, change permissions accordingly)

So if my file looks like:

i have an sql table with 2 columns i run a script that randomly selects a word from the table in column 1.
the word is displayed on the screen and I guess what it means i concatenate the randomly selected word and the answer the script looks for a match in mysql if it finds a match it says "Good job!" if there is no match it will say "not correct". However when i get it right it says not correct even though when i echo the variables they look exactly the same. the script below:
