Unable to assign value in a variable after Substring | Unix Shell Scripting

Something weird happening here, or I couldn't figure out myself.

I am unable to assign value from one variable to other. What I am doing is, retrieving filename and then substring it to check the last 6 letters which is the creation date(yymmdd) of that file, needed for further processing. I have listed 2 different debugging version, which is retriving the filename, but some problem is happening during substring and assigning it to another variable.

• Although during basename itself, it's doing perfect with substring (go to Debugging Version 2)

Debugging version 1:

Code:

fname=''
fdate=''
for file in /home/fimsctl/datafiles/outbound/timelog/timelog_file_*.csv ; do

    echo "Debugging Test: 123"

    fname=` basename $file `

    echo "Debugging Test: 456"

    echo "$fname"

    echo "Debugging Test: 789"

    fdate=` $fname | cut -c2-4 `

    echo "Debugging Test: abc"

    echo "$fdate"

    echo "Debugging Test: def"

  done

Output:

Debugging Test: 123
Debugging Test: 456
timelog_file_150112.csv
Debugging Test: 789
testb.ksh[119]: timelog_file_150112.csv:  not found
Debugging Test: abc

Debugging Test: def

Debugging version 2:

Code:

fname=''
fdate=''
for file in /home/fimsctl/datafiles/outbound/timelog/timelog_file_*.csv ; do

    echo "Debugging Test: 123"

    fname=` ( basename $file ) | cut -c14-19 `

    echo "Debugging Test: 456"

    echo "$fname"

    echo "Debugging Test: 789"

    fdate=` $fname | cut -c2-4 `

    echo "Debugging Test: abc"

    echo "$fdate"

    echo "Debugging Test: def"

  done

Output:

Debugging Test: 123
Debugging Test: 456
150112
Debugging Test: 789
testb.ksh[119]: 150112:  not found
Debugging Test: abc

Debugging Test: def
