Read a file in clojure and ignore the first line?

hope this fix your issue Assuming you'd like to skip the first line of the file and process the remaining lines as you do in tile-image-across, you can simply replace (line-seq rdr) with
(next (line-seq rdr))
;; rename repeat-image to repeat-line

(defn read-image [rdr]
  (next (line-seq rdr)))

(defn repeat-image! [n lines]
  (doseq [line lines]
    (repeat-line n line)))
(with-open [rdr ...]
  (repeat-image! (read-image rdr)))
(->> (line-seq rdr)
     ;; should partition the above into a seq of seqs of lines, each
     ;; describing a single image:
     (partition-into-individual-image-descriptions)
     (map next))

hop of those help? I try to write a batch file that parses a file to create another one with its content. But in the new one I will ignore every line which begin with the -Dremote pattern. , There are a few errors in one line. Try this:
IF NOT "!test:~0,8!"=="-Dremote" (echo %%A>>%iniFile%)

Ignore the rest of the line read after using file.readline(size)

I wish did fix the issue. I have got had an issue. , When you just do:
f.readline()
max_size = 20
with open("test.txt") as f:
    while True:
        l = f.readline(max_size)
        if not l:
            break   # we reached the end of the file
        if l[-1] != '\n':
            # skip the rest of the line
            while True:
                c = f.read(1)
                if not c or c == "\n":  # end of file or end of line
                    break
        print(l.rstrip())

wish of those help I want to be able to read a csv file, decode it with PHP base64_decode() and then write that decoded data to a new file in the same format. , Got it working...just needed to auto-detect line endings.
// without this my code breaks, I'm assuming since my csv has no delimiter it was having issues finding the line endings
ini_set('auto_detect_line_endings', TRUE);
// Store each row in this array
$allRowsAsArray = array();
// open file
if (!$fp=fopen("uploads/".$csv_file,"r")) echo "The file could not be opened.<br/>";

// add each row from col into array
while (( $data = fgetcsv ( $fp , 0)) !== FALSE ) 
{
    $allRowsAsArray[] = $data;
}

// decode array line by line, also add linebreaks back in
foreach($allRowsAsArray as $result) {
    echo base64_decode($result[0])."\n";
}

will be helpful for those in need More I read your question more I get confused about what you're asking. But from what I understood, following should solve your problem.
You can use [IgnoreLast(1)] attribute for this. Number in the attribute indicates how many lines to skip.
