Shell Programming and Scripting

Hi ,
I have moduled my scripts in three scripts .

From First script i am calling second and from second i am calling third for some check .

Problem is with the third script call.

---In second script

Code:

EXP ='test.\abc.\Server.*abc.xml.*'
 
pid=$($HOME/bin/checkpid $EXP)
 
--Third Script --checkpid
pattern=$1
pid=$(pgrep -f $pattern -u $USER)
if [[ -n "$pid" ]]; then
  echo $pid
else
  exit 1
fi

Now when i am directly calling the checkpid script with the expression it is giving me proper result but when i am calling it from the second script ,it is showing me error

Code:

pgrep: option requires an argument -- u
Usage: pgrep [-flvx] [-d DELIM] [-n|-o] [-P PPIDLIST] [-g PGRPLIST] [-s SIDLIST]
        [-u EUIDLIST] [-U UIDLIST] [-G GIDLIST] [-t TERMLIST] [PATTERN]

I have tried putting echo in third script but i am unable to see it in the log file.

Please help me with the same.

Have you verified that the value of $USER is not empty?

ok..will try to check..but i m unable to get output of echo in the third script..thru console value of USER is showing proper but i m calling first script from another application.
