Well, at least the problem with "vi" i can explain:
A file cannot be edited in the same place where it is stored. This is the reason why i.e.
works, while
will not (the same is true for awk, etc.).
Some (GNU-)versions of sed circumvent this principal limitation by introducing inline-editing ("-i"), which works the same way interactive editors like vi do: they create a copy at program start and only upon saving/finishing the work they copy this over the original file.
vi typically uses /var/tmp per default, but can be configured to use other places too (at least to my knowledge all versions of vi offer such an option via the .exrc file). If this filesystem has not enough free space to hold the copy an attempt to edit the file will fail even if there would be enough space in memory to hold it.
Another limitation is the maximum line length: this is a system limitation and how long lines can grow is laid down in the kernel header file limits.h in the constant "LINE_MAX".
Hello,
I need to insert a line (like a header) as the first line of a very huge file (about 3 ml rows). I am able to do it with sed, but redirecting the output and creating a new file takes quite some time. I was wondering if there was a more efficient way of doing it?

Hi,
How can I edit a line in a file?
For example, a.txt contains:
start: 1 2 3 4
stop: a b c d
and I want to change "3" to "9"
and to add "5" after "4"
the result should be (a.txt):
start: 1 9 3 4 5
stop: a b c d
Thanks,

Hi ,
I would like to replace new line characters(\n) in a huge file of about 2 million records . I tried this one (:%s/\n//g) but it's hanging there and no result. Does this command do not work if the file is big. Please let me know if you have any other options

ecppl - language-extractor for ecpp
SYNOPSIS
ecppl [-I dir] [-ln] [-o output-filename] ecpp-filename
DESCRIPTION
Ecppl is the language-extractor for ecpp. Ecpp - the template-language used with tntnet - supports internationalized applications. In
ecpp-templates a tag <i18n> changes the meaning of curly braces. A phrase, which is enclosed in curly braces, can be translated. At run-
time the phrase is looked up in a language-library. This mode can be quit with the tag </i18n>. Phrases must not have newlines or tabs.
Every phrase, which is marked as translatable, is extracted with ecppl and written to standard output or to a specified output-filename
line by line.
OPTIONS -I dir Search include-files in directory. This option can be passed multiple times. All specified directories are searched in turn for
include-files.
-l Extract language-phrases (the default)
-n Extract non-language-phrases
-o filename
Specify output filename
