problem with script and syntax error message
Hi I have the following script and have problem debugging the problems. The function of this script is to make sure the entire file is being received (the filesize of a data is not changing after 20 seconds) and start moving the file to another directory. This script should be started every 30mins.

Code:
#!/usr/bin/ksh
. /opt/Modules/init/ksh

SF_BASAR=/opt/bs/sf
UMC_MASK=/home/umc/dropbox/test
FLAGLIST=/home/umc/dropbox/test/flaglist
FILELIST=/home/umc/dropbox/test/filelist
DIRECTORY=/home/umc/dropbox/datacentre

#store the name of files in bs/sf to filelist
ls -l $SF_BASAR | nawk '{print $9}' > $FILELIST

#compare flag in flaglist with items in $SF_BASAR
#delete flag in flaglist that are not in $SF_BASAR

egrep "$(<$FILELIST)" $FLAGLIST > flaglist.tmp
mv -f flaglist.tmp $FLAGLIST

#if there is an flag in flaglist,exit
NO_OF_FILES=ls /opt/bs/sf/*.gds* | wc -w | nawk '{print $1}'
if (`ls -l $FLAGLIST | nawk `{print $5}'' != "0") then
    exit 1
else
    if ($NO_OF FILES != "0") then
        for i in `ls $SF_BASAR/*.gds*` do
            filesize1=`ls -l $i | nawk `{print $5}''
            sleep 20
            filesize2=`ls -l $i | nawk `{print $5}''

            if $filesize1=$filesize2 then
                #move the file
                mv i $UMC_MASK
                #create flag in flaglist
                echo $i >> FLAGLIST
            fi
        done
    fi
fi
I have the following errors:

Code:
script: /opt/bs/sf/file1.gds.gdz.gpg: cannot execute
0
script[23]: syntax error at line 29 : `filesize1=`ls -l $i | nawk `{print' unexpected

Try this :

Code:
#!/usr/bin/ksh
. /opt/Modules/init/ksh

SF_BASAR=/opt/bs/sf
UMC_MASK=/home/umc/dropbox/test
FLAGLIST=/home/umc/dropbox/test/flaglist
FILELIST=/home/umc/dropbox/test/filelist
DIRECTORY=/home/umc/dropbox/datacentre

#store the name of files in bs/sf to filelist
ls -l $SF_BASAR | nawk '{print $9}' > $FILELIST

#compare flag in flaglist with items in $SF_BASAR
#delete flag in flaglist that are not in $SF_BASAR

egrep "$(<$FILELIST)" $FLAGLIST > flaglist.tmp
mv -f flaglist.tmp $FLAGLIST

#if there is an flag in flaglist,exit
NO_OF_FILES=` ls /opt/bs/sf/*.gds* | wc -w | nawk '{print $1}'`
if (`ls -l $FLAGLIST | nawk '{print $5}'` != "0") 
then
    exit 1
else
    if ($NO_OF FILES != "0") then
        for i in `ls $SF_BASAR/*.gds*` 
        do
            filesize1=`ls -l $i | nawk '{print $5}'`
            sleep 20
            filesize2=`ls -l $i | nawk '{print $5}'`

            if $filesize1=$filesize2 
            then
                #move the file
                mv i $UMC_MASK
                #create flag in flaglist
                echo $i >> FLAGLIST
            fi
        done
    fi
fi

the following command should be in either back quotes or $(..)
we can't directly assign the like this the command ouput

Code:
NO_OF_FILES=`ls /opt/bs/sf/*.gds* | wc -w | nawk '{print $1}'`
here after nawk it should be normal single quote, not back quote.. and after the closed brace }, it should be single quote and then again single back quote...

Code:
if (`ls -l $FLAGLIST | nawk `{print $5}'' != "0") then
if (`ls -l $FLAGLIST | nawk '{print $5}'` != "0")

same thing here again...

Code:
             filesize1=`ls -l $i | nawk `{print $5}''
filesize1=`ls -l $i | nawk '{print $5}'`

check full code again for this kind of errors...

I have changed the script and it look like this now:

Code:
#!/usr/bin/ksh
. /opt/Modules/init/ksh

SF_BASAR=/opt/basar/silicon_foundry
UMC_MASK=/home/umc/dropbox/test
FLAGLIST=/home/umc/dropbox/test/flaglist
FILELIST=/home/umc/dropbox/test/filelist
DIRECTORY=/home/umc/dropbox/datacentre

#store the name of files in basar/silicon foundry to filelist
ls -l $SF_BASAR | nawk '{print $9}' > $FILELIST

#compare flag in flaglist with items in $SF_BASAR
#delete flag in flaglist that are not in $SF_BASAR

egrep "$(<$FILELIST)" $FLAGLIST > flaglist.tmp
#alternative: fgrep -f $FILELIST $FLAGLIST > flaglist.tmp
#alternative: grep -F $FILELIST $FLAGLIST > flaglist.tmp
mv -f flaglist.tmp $FLAGLIST

#if there is an flag in flaglist,exit
NO_OF_FILES='ls /opt/basar/silicon_foundry/*.gds* | wc -w | nawk `{print $1}`'
#alternative: FLAGLIST_CONTENTS='wc -l $FLAGLIST'
if (`ls -l $FLAGLIST | nawk '{print $5}'` != "0") then
        exit 1
else
#       if `ls $SF_BASAR/*.gds*`<>"" then
        if ($NO_OF FILES != "0") then
                for i in `ls $SF_BASAR/*.gds*` do
                        filesize1='ls -l $i | nawk `{print $5}`'
                        sleep 20
                        filesize2='ls -l $i | nawk `{print $5}`'
                
                        if $filesize1=$filesize2 then
                                #move the file
                                mv i $UMC_MASK
                                #create flag in flaglist
                                echo $i >> FLAGLIST
                        fi
                done
        fi
fi
There are stil errors:

syntax error at line 31 : `filesize1="ls -l $i | nawk `{print $5}`"' unexpected

the line should be

filesize1=`ls -l $i | nawk '{print $5}'`


could you please check both the postings made by my self and another friend... you have used the quotes wrongly.. interchanged...

better to use the full code provided by aigles, so that you won't make any mistake...
