我在尝试执行这个bash脚本时在第16行遇到了错误。错误如下：第16行：在意外标记then' line 16:附近出现语法错误，然后muj= ls -l $fajlli | awk '{print $7}' '

# !/bin/bash

if [ -f modified ]
then rm modified
fi
touch modified

muajt=`date | awk '{print $2}'`
ditet=`date | awk '{print $3}'`

tegjithafajllet=`ls`

for fajlli in $tegjithafajllet
do
            if[ -f $fajlli ]
16.         then muj=`ls -l $fajlli | awk '{print $7}'`
            dit=`ls -l $fajlli | awk '{print $8}'`
                 if[ $muajt = $muj -a $ditet = $dit ]
                 then echo $fajlli >> modified
                 fi
            fi
done
