Hi all,

It's my first post on forum - saying HELLO

I have a simple script and would like to improve it.
When [user] in terminal writing correct file name then designed file making grep, etc.But if [user] writing wrong file name then warning should appear in terminal.

This script doesn't work properly. Can you tell me why, please

#!/bin/bash 

##############################################
#Script is taking C,E,V records from P1 file
#
#############################################

#Direction of P1 file
P1_DIR='/home/sprint/Desktop/jacek/test/'
CEV_DIR='/home/sprint/Desktop/jacek/test/cev/'
ERR1="File does not exist - try again with correct file number"

#Some description how it works
echo ""
echo "Hello!"
echo ""
echo "Script will create C, E, V records from P1 file"
echo ""
echo "Type file name without prefix & extension - example 123456023A"
echo ""

read filename

cd $P1_DIR

#It's taking H,C,E,V records from P1 file
if [ -f NSR$filname.p190 ]; then

#It's taking ...
grep ^H NSR$filename.p190 > hdr 
grep ^C NSR$filename.p190 > Crec 
grep ^E NSR$filename.p190 > Erec 
grep ^V NSR$filename.p190 > Vrec 

#it's creating E,V,C records and save as we want :)
cat hdr Erec > "NSR${filename}_Erec.p190" 
cat hdr Vrec > "NSR${filename}_Vrec.p190" 
cat hdr Crec > "NSR${filename}_Crec.p190" 

#cd $P1_DIR
mv $P1_DIR"NSR${filename}_Erec.p190" $CEV_DIR 
mv $P1_DIR"NSR${filename}_Vrec.p190" $CEV_DIR 
mv $P1_DIR"NSR${filename}_Crec.p190" $CEV_DIR 

echo ""


else
    echo "$ERR1"
    exit 1
