Using JSch ChannelSftp: How to list files with path case insensitive

Question

I want to have files with names File1.txt filE2.txt FIle3.txt

I want to list down all three files when I pass the fileMask as a file. basically, I want to do a case insensitive search using the channel.ls(path + fileMask , selector)

Answer 1

To search for a particular file in the sftp location , just do something like :

    remoteFileName = "fileName_[0-9]{08}.txt"
    try {
        ChannelSftp channelSftp = setupJsch();
        channelSftp.connect();
        Vector ls = channelSftp.ls(remoteFilePath);
        Pattern pattern = Pattern.compile(remoteFileName,  Pattern.CASE_INSENSITIVE);
        for (Object entry : ls) {
            ChannelSftp.LsEntry e = (ChannelSftp.LsEntry) entry;
            Matcher m = pattern.matcher(e.getFilename());
            if (m.matches()) {
                //Do something
                channelSftp.get(remoteFilePath + e.getFilename(), getLocalFileDir());
                channelSftp.exit(); //If you want to search for multiple files then do not terminate the connection here
            }
        }
    } catch (JSchException jSchException) {
        LOGGER.info("File download failed :", jSchException);
    } catch (SftpException sftpException) {
        LOGGER.info("File download failed :", sftpException);
    }
