I have a main script with while loop having for loop inside. Again in for loop based on if condition few functions will be called. So when a function is called for certain condition it should come out from the main for loop and should continue with while loop. Let me explain with example here: I am having a ksh as below
Code:
###Functions#####execute_sqlldr(){sqlldr user/pass control=$ctl log=$log data=$file discard=$disRC=$? if [$RC -eq 0] then echo "loaded successfully" elif [$RC -eq 1 -o $RC -eq 3]; then echo "sqlldr problem" elif [$RC -eq 2]; then ?? fireturn 0}execute_sp(){-----}###Main Program####while [1]do for file in `ls /home/usr/*.txt` do if grep 'Oracle Available'; then execute_sqlldr $file else echo "database is not available" fi execute_sp $file donedone
Here in the main program when execute_sqlldr $file is called and when $RC -eq 2 then my program instead of coming back to for loop in main program and calling the next function execute_sp $file it should come wholly out of for loop and should start from while loop. So with what should i replace ?? with in the function execute_sqlldr(). I hope i am clear here. Any help is greatly appreciated. Thanks

truncate
TRUNCATE(1) User Commands TRUNCATE(1)NAME
truncate - shrink or extend the size of a file to the specified size
SYNOPSIS
truncate OPTION... FILE...
DESCRIPTION
Shrink or extend the size of each FILE to the specified size
A FILE argument that does not exist is created.
If a FILE is larger than the specified size, the extra data is lost. If a FILE is shorter, it is extended and the extended part (hole)
reads as zero bytes.
Mandatory arguments to long options are mandatory for short options too.
-c, --no-create
do not create any files
-o, --io-blocks
treat SIZE as number of IO blocks instead of bytes
-r, --reference=RFILE
base size on RFILE
-s, --size=SIZE
set or adjust the file size by SIZE bytes
--help display this help and exit
--version
output version information and exit
The SIZE argument is an integer and optional unit (example: 10K is 10*1024). Units are K,M,G,T,P,E,Z,Y (powers of 1024) or KB,MB,... (pow-
ers of 1000).
SIZE may also be prefixed by one of the following modifying characters: '+' extend by, '-' reduce by, '<' at most, '>' at least, '/' round
down to multiple of, '%' round up to multiple of.
