Shell script replied multiple process for file has successfully created
Hi All,
I have written the following code
Code:
do
FILE_NO=$(echo $LINE|awk -F"|" '{print $1}'|tr "'" '+'|sed 's/\(.*\)\(++\)\(.*\)\(++\)/\3/')
INST_NO=$(echo $LINE|awk -F"|" '{print $2}'|tr "'" '+'|sed 's/\(.*\)\(++\)\(.*\)\(++\)/\3/')
if [[ -e ${TMP_LOC}/${FILE_NO}_${INST_NO}.lck ]]
then
LOG_PRINT `basename $0` "Duplicate file lck: ${TMP_LOC}/${FILE_NO}_${INST_NO}.lck"
continue
else
touch ${TMP_LOC}/${FILE_NO}_${INST_NO}.lck
if [[ $? -ne 0 ]]
then
LOG_PRINT `basename $0` "Unable to create lck file : ${TMP_LOC}/${FILE_NO}_${INST_NO}.lck"
continue
fi
LOG_PRINT `basename $0` "Successfully lck file : ${TMP_LOC}/${FILE_NO}_${INST_NO}.lck created"
fi
LOG_PRINT `basename $0` "Processing OUTPUT PARAM : $LINE"
PARAM_FLAG=1
i=$( expr $i + 1 )
break
done
But When I run 30 instance (same time via cron) of the script multiple output comes on the script stating that "Successfully lck file created" with same name.
Please help

basename
basename(1B) SunOS/BSD Compatibility Package Commands basename(1B)NAME
basename - display portions of pathnames
SYNOPSIS
/usr/ucb/basename string [suffix]
DESCRIPTION
The basename utility deletes any prefix ending in `/' and the suffix, if present in string. It directs the result to the standard output,
and is normally used inside substitution marks (` `) within shell procedures. The suffix is a string with no special significance attached
to any of the characters it contains.
EXAMPLES
Example 1: Using the basename command.
This shell procedure invoked with the argument /usr/src/bin/cat.c compiles the named file and moves the output to cat in the current direc-
tory:
example% cc $1
example% mv a.out `basename $1 .c`
