actually file checking on remote server ayithe perl best. Login to remote server with credentials and do listing on the filename and write it to an array and then disconnnect from remote host and check if the array is empty.. shell lo ayithe remote host meeda file test cheyalem.. you gotta get the filename someway to local host and then do the file test.

if your calling program is also shell script then parent you can do like this rc=`call child program` and capture return code in $rc Just Sports! | ||

that is for the unix command with in the script.. grep -i "check" /tmp/file1 if test $? -ne 0 ; then the above you are checking for the grep command.. what i am asking is after i found $? -ne 0 the script should return to the calling command with failure status.. | ||

I would say go for perl script rather than shell. Shell lo 2 passes lo chesedi perl lo 1 pass lo cheyochu. And if your company mandates sftp which most of the companies are doing now..then it is much easier to manage in perl script over shell script. Just Sports! | ||

generally 0 is considered as success and 1 is failure! if I understand correctly you wnted to exit, your shell script with error code. if thats the case, use exit 1 | ||

ee programming language lo ina check sesukovachu file vunda leda anedhi!! not a big deal! but how frequently it shud check for file ? You need another program / command like cron to schedule this program! u can just write a shell loop and check for this file, if its unavailable, throw some message and get back to sleep mode! if ur intention is to load the data into oracle, oracle lo inbuilt feature vundi...sftp/ftp chesi file download chesi, process chesi load cheyyatam !!file leka poteh ignore madithi! | ||

if I got this str8 1. program written in a language like C, cpp, java etc downloads file from file server 2. program calls unix script to do something with the file if file is not available for step2...report failed status and quit program? if yes, programming language's file API should have a fileExists(String filePath) function or similar- that should be enough to check and quit prg withot calling unix script | ||

i have to call a script from another program. the program gets the file from the client server through FTP and processes the file. The file frequency is unknown, usually twice a month but with no fixed dates. I want a script that checks for the file and should give me failed status if not exists so that i can quit the program with out processing. |
