This is a very simple function called i_upper_case , you can probably guess what it does. The backslash at the end of the echo line is a UNIX feature that allows a command line to be continued on the next line. It tells the system to ignor the next character - in this case the newline. Note that it gets its input argument from a passed parameter ($1). So to make use of this function within a script you simply need to call it with an argument as follows:
So when I created a function as follows
Code:
######Set Path Variables
echo -==Set Path Variables==- > `cat /export/home/mldwh/rkem_refresh/logs/rkem_log_dir`$TEST
RKEM_LOG=`cat /export/home/mldwh/rkem_refresh/logs/rkem_log_dir`
RKEM_SCRIPT=`cat /export/home/mldwh/rkem_refresh/logs/rkem_script_dir`
RKEM_LOAD_FILES=`cat /export/home/mldwh/rkem_refresh/logs/rkem_load_dir`
echo -==RKEM_LOG $RKEM_LOG==- >> $RKEM_LOG$TEST
echo -==RKEM_SCRIPT $RKEM_SCRIPT==- >> $RKEM_LOG$TEST
echo -==RKEM_LOAD_FILES $RKEM_LOAD_FILES==- >> $RKEM_LOG$TEST
######Set Username and Password Variables
echo -==Set Password Variables==- >> $RKEM_LOG$TEST
IDB1USER=`cat /export/home/mldwh/maintenance/connectivity/idb1user.txt`
IDB1PWD=`cat /export/home/mldwh/maintenance/connectivity/idb1pwd.txt`
TPCUSER=`cat /export/home/mldwh/maintenance/connectivity/tpcuser.txt`
TPCPWD=`cat /export/home/mldwh/maintenance/connectivity/tpcpwd.txt`
echo -==IDB1USER $IDB1USER==- >> $RKEM_LOG$TEST
echo -==IDB1PWD $IDB1PWD==- >> $RKEM_LOG$TEST
echo -==TPCUSER $TPCUSER==- >> $RKEM_LOG$TEST
echo -==TPCPWD $TPCPWD==- >> $RKEM_LOG$TEST
RKEM_Mainframe_time ()
{
######Connect to IDB1 and capture the current time of the system
echo -==Connect to IDB1 and capture the current time of the system==- >> $RKEM_LOG$TEST
db2 "connect to idb1 user $IDB1USER using $IDB1PWD" >> $RKEM_LOG$TEST
db2 -x "select current timestamp from sysibm.sysdummy1" > $RKEM_LOG"rkem_mainframe_system_date_time.txt"
db2 -x "select current date from sysibm.sysdummy1" > $RKEM_LOG"rkem_mainframe_system_date.txt"
db2 -x "select current time from sysibm.sysdummy1" > $RKEM_LOG"rkem_mainframe_system_time.txt"
db2 Terminate
echo -==Mainframe System Date Time `cat $RKEM_LOG"rkem_mainframe_system_date_time.txt"`==- >> $RKEM_LOG$TEST
echo -==Mainframe System Date `cat $RKEM_LOG"rkem_mainframe_system_date.txt"`==- >> $RKEM_LOG$TEST
echo -==Mainframe System time `cat $RKEM_LOG"rkem_mainframe_system_time.txt"`==- >> $RKEM_LOG$TEST
}
And then do the following SH script
Code:
TEST="TESTLOG.LOG"
RKEM_Mainframe_time $TEST
The function works correctly. Is there any danger concerning this variable not getting set correctly by calling it this way?
Remember the $1 from the example you found? You can refer to the function arguments using $1 - $9. When you use $TEST in your function it isn't reading a parameter - it's reading an outside variable definition. By not using $1 you actually lose some functionality.
The other thing of some interest is the assignments you make using cat /somefile. First off, the cat is not necessary - but second, and more importantly be aware that assigning this data to a variable has a compressing effect.
Wow Dude u just blew my mind...If what I think you said is what you actualy said WOW can i go places.
First of about using cat:
Quote:
echo -==Mainframe System Date Time `cat $RKEM_LOG"rkem_mainframe_system_date_time.txt"`==- >> $RKEM_LOG$TEST
What I am trying to do here is take the data that is in the variable $RKEM_LOG and append the "rkem_mainframe_system_date_time.txt" to create a full path. Is this where you mention my improper use of cat or was it here:
This is where I read what is in this file which is the text string that makes up the begining of the path. I am doing this so that I can move these scripts around and not have to recode. Should I be using syntax that looks like this:
Here rkem_log_dir is actualy a file that contains the desired text. The goal again was that if i needed to change path locations I would only have to change the file and the one set of code that sets the path variables...
What does the < stand for?
Also I did not see what you ment by whey you said that CAT causes compresion. Both outputs looked the same to me...
As for the variables...
Quote:
By not using $1 you actually lose some functionality.
Does the $1 indicate the first variable?...Meaning that if I had a second variable then I would use $2?
If what I am saying is true then it should look something like this
OLD CODE
Code:
RKEM_Mainframe_time ()
{
######Connect to IDB1 and capture the current time of the system
echo -==Connect to IDB1 and capture the current time of the system==- >> $RKEM_LOG$TEST
NEW CODE
Code:
RKEM_Mainframe_time ()
{
######Connect to IDB1 and capture the current time of the system
echo -==Connect to IDB1 and capture the current time of the system==- >> $1$2
And to call this I would do something like this
Code:
RKEM_Mainframe_time '/export/home' 'Filename'
Am I just totaly out of my mind or did I actualy figure out something?

If you check the manpage for cat you'll see that it's used to concatenate files. When you're making variable assignments you don't need to use cat. Just go ahead and do this:
I made the comment about the compression because I mistakenly thought you were trying to get the data in the files rather than assigning the names of the files. Since we brought it up, though check out the actual file listing versus the output of the variables they were assigned to. In both instances the linebreaks were removed and the whole file ended up on one line. This could be a pitfall if you attempted to do a sed or grep on that data.
I threw an extra '/' character in the lines with '$RKEM_LOG/$TEST' under the assumption that the variables are directory name and file name.
Regarding the backticks `` or $() - you'll need to sed s#/bin/sh#/bin/bash#g my previous posts where I used the $() as I don't recall this being available in standard Bourne shell. Go with the `` for portability.

You got it.
The only thing is when you make the call do something like:
Code:
RKEM_Mainframe_time /export/home/ Filename
or
Code:
RKEM_Mainframe_time /export/home /Filename
or better yet combine your variables in the function like this:
OK here goes one more example. Im going to try this but wanted another set of eyes on this.
I have a function that sets the path variables, lets call it THE_PATH. One of the variables is called RKEM_LOG. There is a / embeded at the end of the variable definition. I have another function called RKEM_Mainframe_time. In this function I use the variables $1 and $2. Will this work:
