Hi,
I need a unix command to delete first n (say 100) lines from a log file. I need to delete some lines from the file without using any temporary file. I found sed -i is an useful command for this but its not supported in my environment( AIX 6.1 ). File size is approx 100MB.

The dataset I'm working on is about 450G, with about 7000 colums and 30,000,000 rows.
I want to extract about 2000 columns from the original file to form a new file.
I have the list of number of the columns I need, but don't know how to extract them.
Thanks! (14 Replies)

shar
SHAR(1net) Wang Institute SHAR(1net)NAME
shar - create file storage archive for extraction by /bin/sh
SYNOPSIS
shar [-abcmsuv] [-p prefix] [-d delim] files > archive
DESCRIPTION
shar prints its input files with special command lines around them to be used by the shell, /bin/sh , to extract the files later. The out-
put can be filtered through the shell to recreate copies of the original files.
shar allows directories to be named, and shar prints the necessary commands (mkdir & cd) to create new directories and fill them. shar
will not allow existing files to be over-written; such files must be removed by the user extracting the files.
OPTIONS -a All the options. The options: -v -c -b -p <tab>X are implied.
-b Extract files into basenames so that files with absolute path names are put into the current directory. This option has strange
effects when directories are archived.
-c Check file size on extraction by counting characters. An error message is reported to the person doing the extraction if the sizes
don't match. One reason why the sizes may not match is that shar will append a newline to complete incomplete last lines; shar
prints a message that mentions added newlines. Another reason why the sizes may not match is that some network mail programs remove
non-whitespace control characters. shar prints a message that mentions control characters to the extractor.
-d Use this as the ``end of file'' delimiter instead of the default. The only reason to change it is if you suspect a file contains
the default delimiter: SHAR_EOF.
-m Reset the exact protection modes of files when they are extracted (using the chmod program). By default, the extractor's default
file modes are used, and executable files (e.g., shell scripts) are made executable.
-p Use this as the prefix to each line of the archived files. This is to make sure that special characters at the start of lines are
not eaten up by programs like mailers. If this option is used, the files will be extracted with the stream editor sed rather than
cat so it is more efficient and portable to avoid setting the prefix, though perhaps less safe if you don't know what is in the
files.
-s Silent running. All checking and extra output is inhibited.
-u Archive the input files with the uuencode format for later extraction with uudecode. This will allow you to send files with control
characters in them, but will slow down the extracting. You must be sure that the receiving party has access to uudecode.
-v Print verbose feedback messages about what shar is doing to be printed during extraction. Sizes of plain files are echoed to allow
a simple validity check.
