Echoing statements in bash script

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

Using a bash script I want to echo several strings to a file. The echo statement, however, is in a function and thus indented but I do /not/ want the strings echoed indented in the new file. Is this doable?

Here is an example:

f () {

    echo "

    # this is a test


    b=456" > file.txt


File.txt should the contain:

# this is a test



Thus no indentation. It seems that if I prepend each line with \b the line should be backspaced which would work nicely but the echo statement seems to replace a backspace within the quotes to spaces...
