small problem with ksh at aix

sukhdip · 05-23-2012, 02:02 AM

Hi!

I made a shell script which is offering menu choice. I made it on RHEL & then with little bit changes I was able to run successfully on AIX/ksh.
Script is working fine with no issues other than a little one i.e., There is one choice in which I can list out and delete some files from a directory as per userinput. If there are files it listing and deleting without any problem but if there ain't any files then its displaying one error.
i.e.,
find: 0652-019 The status on 1_*.* is not valid.

Here is my script:

Code:

#!/usr/bin/ksh


script_menu() {
while :
       do
       clear
echo ----------------------------------------------
echo   ************Script Start Menu************
echo ----------------------------------------------
echo Run from the following Scripts
echo   
       echo [1] xyz.sh
       echo [2] abc.sh
       echo [3] Return to Main Menu
       echo [4] Exit
echo ----------------------------------------------
read choice
case $choice in
1)
       echo Run xyz script file; /backup/test1/xyz.sh;
       echo Press Enter; 
       read x;;
       
2) 
       echo Run abc script file; /backup/test1/abc.sh;
       echo Press Enter; 
       read x;;
3)     
       return;;
4)
       exit;;
    esac 
 done
}


#Main Menu
while :
       do
       clear
       echo ----------------------------------------------------
       echo    ******************Main Menu******************
       echo ----------------------------------------------------
       echo Select a Choice
       echo [1] Run the Scripts
       echo [2] View the Current Run Numbers
       echo [3] Amend the Run Numbers
       echo [4] Check Status of propagation 
       echo [5] Turn Propagation on or off
       echo [6] View Log Files
       echo [7] List files in import directory
       echo [8] Clear files from import directory
       echo [9] Exit
       echo ----------------------------------------------------
       echo Select choice {1-9}:
read choice

case $choice in
1)
       script_menu;;

2) 
       echo Current Run Number; cat /backup/test1/run_number.txt; 
	   echo Press Enter; 
       read x;;

3)     echo Enter Run Number;
       read -r  userinput; echo $userinput > run_number.txt; 
       echo Press Enter;
       read x;;  
4)
       echo Propagation Status ; cat /backup/test1/auto_pro.txt; 
	   echo Press Enter; 
       read x;;

5)
       echo Change Propagation ; echo Enter Value; read -r  userinput; echo $userinput > auto_pro.txt; 
       echo Press Enter; 
       read x;; 

6)     
       echo View Log files; 
       echo Enter Log file name;
       read -r filename ; echo $filename | ls -l | find "$filename"_*.* -type f ! -name ".*" | awk '{print}'; 
       echo Press Enter; 
       read x;;
7)
       echo List files in import directory;
       echo Enter file name;
       read -r filename ; echo $filename | ls -l | find "$filename"_*.* -type f ! -name ".*" | awk '{print}';
       echo Press Enter; 
       read x;;
8)
       echo Clear files from import directory;
       echo Enter File Name;
       read -r filename ; echo $filename | ls -l | find "$filename"_*.* -type f ! -name ".*" -exec rm -f {} \;
       echo Press Enter;
       read x;;
9)   
       exit;;
*) 
       echo Invalid Number
       

    esac
done

option number 6,7,8 are giving above error, If there is no files with the name as input by user.
How can I solve this? Plz help !!

Thanks,

As per my understanding, command is working fine i.e., find command. B'coz on RHEL machine its showing: 5_*.*: No such file or directory
but on AIX machine its showing: find: 0652-019 The status on 1_*.* is not valid.
I guess context is the same of both saying.
So what I'm thinking to do(now) that How can I put a customized message like: "No file with this name", when there is no file.
Plz help me with that.

sukhdip · 05-23-2012, 06:13 AM

plz help!!
Simple thing i have to do. How can I print my own message when file is not found by find command.

3-4 days to a thread....no reply for the questions

what happened Unix Gurus...plz help

pan64 · 05-25-2012, 01:24 AM

I think noone understand your script. What should do this line:

Code:

read -r filename ; echo $filename | ls -l | find "$filename"_*.* -type f ! -name ".*" | awk '{print}';

ls does not accept anything from stdin, so here: echo $filename | ls -l the red part is useless. also the | before find is meaningless. | awk '{print}' does nothing.

sukhdip · 05-25-2012, 01:49 AM

awk '{print}'is useless that i came to know. But ls -l is taking input from echo $filename and its printing the filenames only if the files are there. and if the files are not there it printing:
1_*.*: No such file or directory on RHEL plateform.
find: 0652-019 The status on 1_*.* is not valid. on AIX plateform.
problem is this i need to print some customized message instead of these messages. Like in Simple plain english it should say. File is not present or something like that.
how to print that my question is that...
Hope you got my point.

1_ is a randome file name, used to check.

Sorry, I do not understand:

Quote:

ls -l is taking input from echo $filename and its printing the filenames only if the files are there.

executing echo <anything> | ls -l will give the same result as ls -l alone (at least on RH, but I think on AIX also).
If you think it is not the case just show me how it works.
find also cannot handle pipe as input. If you want to check if $filename was valid, you would try [[ -f "$filename" ]] && find .... If you want to check if it was a directory, type [[ -d "$filename" ]] && find .....

thanks alot @pan64. u r absolutely ryt. I was using some unnecessary commands. i.e., ls,echo,awk. I'm a newbie in scripting. so from these type of experiences I will learn. as today I learned from your reply.
and somehow searching I made it to run.
again thanks for your help.

pan64 · 05-25-2012, 06:49 AM

I'm glad to help you.
