A “here document” is a way to specify multiple lines of text as the input to a command in a shell script. In a bash script, you can use a here document to write data to a file. Here’s an example of how to use a here document to write data to a file:<\/p>\n

\n
\u00a0<\/div>\n
#!\/bin\/bash<\/span><\/p>\n

# The file to write to<\/span>
\nfile=\"test.txt\"<\/span><\/p>\n

# The data to write to the file<\/span>
\ncat<\/span> << EOF > \"$file\"
\nThis is a line of text.
\nThis is another line of text.
\nAnd this is yet another line.
\nEOF<\/span>
\n<\/code><\/div>\n<\/div>\n

In this example, the cat<\/code> command writes the lines of text contained within the here document to the file specified by \"$file\"<\/code>. The > \"$file\"<\/code> operator is used to redirect the output of cat<\/code> to the file. The marker EOF<\/code> is used to indicate the end of the here document. Note that you can use any string as the marker, but it should not appear anywhere within the text of the here document.<\/p>\n","protected":false},"excerpt":{"rendered":"
