I'm trying to split a string of this kind :
file1 -> file2
and expect to affect "file1" and "file2" to 2 variables.
I tried with IFS but it seems to work only for one character long (with IFS=" -> " I get "file1" and "> file2"...
Based on this article, I tried another approach :
awk 'BEGIN {FS=" -> "} {xxx}' <<< $f
The issue is that I don't succeed to affect $1 and $2 to a variable that I could use later...
You can do this in several ways:
str="file1 -> file2"
echo "Fast"
var1="${str% -> *}"
var2="${str#* -> }"
printf "%s=%s.\n" var1 "${var1}" var2 "${var2}"
echo "With cut"
var1="$(echo ${str}|cut -d" " -f1)"
var2="$(echo ${str}|cut -d" " -f3)"
printf "%s=%s.\n" var1 "${var1}" var2 "${var2}"
echo "With read"
read -r var1 arrow var2 <<< ${str}
man read doesn't help a lot...
You can use $():
VARIABLE="$(awk 'BEGIN {FS=" -> "} {for(i=1;i<=NF;i++)print $i}' <<< $f)"
You can assign the results to an array:
ARRAY=( $(awk 'BEGIN {FS=" -> "} {for(i=1;i<=NF;i++)print $i}' <<< $f) )
And extract the values as separate variables:
${ARRAY[0]}
${ARRAY[1]}
and so on...
And assign it to your variables.
