I have a text file that has many lines, and for each line I need to extract different sections of text, then write several variables from the data.
I can split out the various sections by selecting their position on each line as the column sizes will never vary.
A sample of my text file is below
Code:
"A 16 7G12Cooper Amber 4"
"A 16 9G12Patrech Erin 4"
"A 16 12B12Donovan Brody 4"
"A 16 14G12Tanea Semira 4"
"A 16 70 G9Fink Jade 4"
"A 16 72 B8Srini Sandip 4"
"A 16 938G12Calvar Ashley 4"
the variables and selection criteria i am extracting is here
Code:
file="Names.EXT"
while read line
do
echo $line
genderage=${line:9:3} #Loc 9th character in the line and select the next 3 Char
lastnam=${line:12:20} #loc 12th character in the line and select the next 20 char
firstnam=${line:32:21} #loc 32nd character in the line and select the next 21
echo "$lastnam;$firstnam;;$gend;$age;;" >> MM_file.txt
done <"$file"
Now to my specific Question,
for the variable $genderage, I need to delete the first character ( either B or G) and write a new variable called $gend that is either M or F depending on the original letter.
the remaining number could be either a 1 or 2 digit number which I need to write to another veriable $age.
the other question is how to delete all the trailing spaces from the other 2 variables? this can be done either when selection them, or when writing them out to a new file.
$lastnam
$firstnam
TIA
Ken

Did you peruse your shell's man page? This works with recent shells:
Code:
while read line
do #echo $line
gendage=${line:9:3} #Loc 9th character in the line and select the next 3 Char
gendage=${gendage##* }
[ "${gendage:0:1}" = "B" ] && gend="M" || gend="F"
age=${gendage:1}
lastnam=${line:12:20} #loc 12th character in the line and select the next 20 char
lastnam=${lastnam%% *}
firstnam=${line:32:21} #loc 32nd character in the line and select the next 21
firstnam=${firstnam%% *}
echo "$lastnam;$firstnam;;$gend;$age;;"
done < file
Cooper;Amber;;F;12;;
Patrech;Erin;;F;12;;
Donovan;Brody;;M;12;;
Tanea;Semira;;F;12;;
Fink;Jade;;F;9;;
Srini;Sandip;;M;8;;
Calvar;Ashley;;F;12;;
Thanks Rudi
I have read so much over the last few days re this and did not even think to use the shell. Looking at awk, sed and such and probably making life hard at the same time!
when at home later i will update my script accordingly

I have 1 file that has elements as follows. Also the CVR(10) and the word "SAUCE" only appear once in the file so maybe a grep command would work?
