Top Forums UNIX for Dummies Questions & Answers Count Number Of lines in text files and append values to beginning of file Post 302517767 by alister on Wednesday 27th of April 2011 05:19:10 PM
Old 04-27-2011
For a UNIX system, I like:
Code:
for f in *; do
        l=$(wc -l < "$f")
        [ $l -lt 400 ] && continue
        ed -s "$f" <<-EOED
                0a
                there are 400 lines in this file and $((l-400)) bonus lines
                .
                w
                q
        EOED
done

Caveat: All the leading whitespace from "<<-EOED" to "EOED" must be tab characters, not spaces.

Regards,
Alister

CURLOPT_FAILONERROR(3)					     curl_easy_setopt options					    CURLOPT_FAILONERROR(3)

NAME
CURLOPT_FAILONERROR - request failure on HTTP response >= 400 SYNOPSIS
#include <curl/curl.h> CURLcode curl_easy_setopt(CURL *handle, CURLOPT_FAILONERROR, long fail); DESCRIPTION
A long parameter set to 1 tells the library to fail the request if the HTTP code returned is equal to or larger than 400. The default action would be to return the page normally, ignoring that code. This method is not fail-safe and there are occasions where non-successful response codes will slip through, especially when authentication is involved (response codes 401 and 407). You might get some amounts of headers transferred before this situation is detected, like when a "100-continue" is received as a response to a POST/PUT and a 401 or 407 is received immediately afterwards. When this option is used and an error is detected, it will cause the connection to get closed. DEFAULT
0, do not fail on error PROTOCOLS
HTTP EXAMPLE
TODO AVAILABILITY
Along with HTTP RETURN VALUE
Returns CURLE_OK if HTTP is enabled, and CURLE_UNKNOWN_OPTION if not. SEE ALSO
CURLOPT_HTTP200ALIASES(3), CURLOPT_KEEP_SENDING_ON_ERROR(3), libcurl 7.54.0 September 22, 2016 CURLOPT_FAILONERROR(3)
