1 year ago
by Fahmida Yesmin

>> Very good examples!!!

+---+
#!/bin/bash
# Read a string with spaces using for loop
for value in I like programming
do
    echo $value
done

+---+
#!/bin/bash
#Declare a string array
LanguageArray=("PHP"  "Java"  "C#"  "C++"  "VB.Net"  "Python"  "Perl")
# Print array values in  lines
echo "Print every element in new line"
for val1 in ${LanguageArray[*]}; do
     echo $val1
done
 
echo ""
 
# Print array values in one line
echo "Print all elements in a single line"
for val2 in "${LanguageArray[*]}"; do
    echo $val2
done
echo ""

Create a new bash file named ‘for_list6.sh’ with the following code. Here, comma (,) is used to split the string values.  IFS variable is used to set the field separator.
#!/bin/bash
DataList=" HTML5, CCS3, BootStrap, JQuery "
Field_Separator=$IFS
 
# set comma as internal field separator for the string list
IFS=,
for val in $DataList;
do
echo $val
done
 
IFS=$Field_Separator
