writing to a file

ravi2ray · 10-29-2008, 02:57 PM

I am looking for help on writing to a text file:

Lets say i have a file name text.text and i want to echo out "enter name"
then echo "enter age". The collected information i would like to append it to a file that is created when the function is called:

function addText() {

name=$1
age=$2

folder="$HOME/dir/"

fileName=${folder}dir${age}.txt
tempFile=${folder}films${name}Temp.txt

echo "$name" >> $fileName

}

input:
Enter Name: Raymond
Enter Age: 20

next input:

enter name: ray
enter age: 22

the Output inside the file should look like:

"Raymond", "20"
"ray", "22"

... etc.

#!/bin/bash
folder="$HOME/dir"
fileName=${folder}/text.text
read -p "Name " name
read -p "Age " age
echo "\"$name\",\"$age\"" >>${fileName}

If you are doing a lot of lines all at once... it is best to do the following

Code:

MYVAR=123

# use > to write over the whole file
# use >> if you want to append to the end

cat > file_name << EOF_ANYTHING_GOES_HERE
this is all text treated
as if it was quoted with ""
you can use variables such as \$MYVAR=$MYVAR
and you can use commands like: `date`

To end the file, place a matching phrase from after the << right up against the
left side.  DO NOT INDENT! that requires <<-SOMETHING_ELSE

EOF_ANYTHING_GOES_HERE

I don't have a linux box with me at work... BUT that will get you headed in the right direction.
the ` mark on `date` is the mark from the tilde~ key

I use this method when i need to build a dynamic menu for blackbox/openbox

Generally, you do not want to tack something like this onto an existing thread---particularly an old one. I'm splitting this out to a separate thread.
