Hello, let's say I have this string:
string1="A\nB\nC D E\nFG\nH";
How can I split it so as to take every string separated with '\n' separately?
For example, as for $string1, it would be split into
string1_part1="A"
string1_part2="B"
string1_part3="C D E"
string1_part4="FG"
string1_part5="H"
i tried to do this way:
for i in $string1; do
mpla mpla
done
but this way takes spaces as separators too, so that didn't work 
Thanks in advance for any answers!
#!/usr/bin/bash
string1="A\nB\nC D E\nFG\nH";
echo $string1 >temp
while read a
do
echo "$a"
done <temp
Yes it's possible but I'm sure you don't need it.
Did your try your string in bash:
string1="A\nB\nC D E\nFG\nH"
echo "$string1"
I believe you need learn some basic stuff before. The semicolon at the end of the assignment says about this too.
What about this:
#!/bin/bash
## Define a string
string1="A\nB\nC D E\nFG\nH"
## Replace the \n's with a single character, since IFS
## can only be 1 character.
match='\\n'
replacement='|'
string2=$(echo ${string1//${match}/${replacement}})
## Change the input field seperator to $replacement
IFS="$replacement"
## Parse the string based on the IFS.
set -- $string2
echo "1: $1"
echo "2: $2"
echo "3: $3"
echo "4: $4"
echo "5: $5"
Output:
$ test2
1: A
2: B
3: C D E
4: FG
5: H
$
Simpler way for bash or newer ksh or even ash:
#!/bin/bash
string1="A\nB\nC D E\nFG\nH"
OLDIFS="$IFS"
IFS="
"
set -- `echo -e "$string1"`
IFS="${OLDIFS}"
echo $1
echo $2
echo $3
echo $4
In some shells you can remove the -e.
