Display match or no match and write a text file to a directory
The below bash connects to a site, downloads a file, searches that file based of user input - could be multiple (all that seems to work). What I am not able to figure out is how to display on the screen match found or no match found" and write a file to a directory (C:\Users\cmccabe\Desktop\wget) with the match in it. If there is no match then no file needs to be created just displayed. Thank you .
Code:
#!/bin/bash
# url download
printf "establishing connection and downloading file, please wait"
cd 'C:\Users\cmccabe\Desktop\wget'
curl -# -o getCSV.txt http://xxx.xx.xxx.xx/file/name.csv
# enter user-defined id
printf "please enter id(s), use a comma between multiple: "; IFS="," read -a id
# check to make sure something entered
[ -z "$id" ] && printf "\n No ID supplied. Leaving match function." && sleep 2 && return
# search download using entered id
echo "searching, please wait"
result=`grep -n "${id}" getCSV.txt`
for ((i=0; i<${#id[@]}; i++))
do printf ${id[$i] & ${result[$i]}} >> "C:\Users\cmccabe\Desktop\wget\match.txt"
done
printf "match found in line $result"
else
printf "No match found! " && sleep 2
fi
# additional
printf "Are there additonal patients? Y/N "; read match_choice
case "$match_choice" in
[yY]) id="${id}"; echo "what is the id of the NGS patient: "; read id
[ -z "id" ] && printf "\n No ID supplied. Leaving match function." &&
sleep 2 && exit
