I have this script
for ((i=0 ; $i<=$c ; i++))
do
cat <<"EOF" >my_file.html
line 1
line 2
...
EOF
done
It is supposed to write some specific lines in each loop but my file is empty and i always get this error
syntax error: unexpected end of file
Before this loop i have another use of cat exactly like this
cat <<"EOF" >my_file.html
line1
...
line n
EOF
After running the script my_file.html contains these n lines but none of the loop lines.
Your syntax is wrong.
You have a space before the delimiter denoting the end of here-doc.
cat <<"EOF" >my_file.html
line 1
line 2
...
EOF # Remove the leading space from this line.
Additionally, if you want to redirect within a loop you probably wanted to append >> instead of redirecting >.
EOF (see edit above.> which truncates the file. In order to append to the file, use >>.Make sure that you do not have any whitespace before or after the EOF delimiter, otherwise the shell won't be able to find the end of the here-document and you will get an unexpected end of file error.
This line should only contain the delimiter word (EOF) and nothing else. Not even comments.
cat <<"EOF" >my_file.html
line 1
line 2
EOF
# there should not be any whitespace around EOF on the line above
