Help with changing header of tsv with 30 million lines
Hi
My 30 million line file has a header
I want to replace all instances of s1 to s4 with L1 to L4 and then all instances of s5 to s8 with W1 to W4 in the header using a shell script so I don't have to use an editor.
I realise I can use something like
but what form would a shell script need to take to do this on multiple files?
Hello,
Does changing a header in a shared library under Solaris (say adding a new class data member) will result in not only compiling that library but all of the libraries that depend on that lib that was changed because of the change in the object's size? What about adding a virtual function?... (0 Replies)

Locale::Script - standard codes for script identification
SYNOPSIS
use Locale::Script;
$script = code2script('phnx'); # 'Phoenician'
$code = script2code('Phoenician'); # 'Phnx'
$code = script2code('Phoenician',
LOCALE_CODE_NUMERIC); # 115
@codes = all_script_codes();
@scripts = all_script_names();
DESCRIPTION
The "Locale::Script" module provides access to standards codes used for identifying scripts, such as those defined in ISO 15924.
Most of the routines take an optional additional argument which specifies the code set to use. If not specified, the default ISO 15924
four-letter codes will be used.
SUPPORTED CODE SETS
There are several different code sets you can use for identifying scripts. The ones currently supported are:
alpha
This is a set of four-letter (capitalized) codes from ISO 15924 such as 'Phnx' for Phoenician.
This code set is identified with the symbol "LOCALE_SCRIPT_ALPHA".
The Zxxx, Zyyy, and Zzzz codes are not used.
This is the default code set.
numeric
This is a set of three-digit numeric codes from ISO 15924 such as 115 for Phoenician.
This code set is identified with the symbol "LOCALE_SCRIPT_NUMERIC".
ROUTINES
code2script ( CODE [,CODESET] )
script2code ( NAME [,CODESET] )
script_code2code ( CODE ,CODESET ,CODESET2 )
all_script_codes ( [CODESET] )
all_script_names ( [CODESET] )
Locale::Script::rename_script ( CODE ,NEW_NAME [,CODESET] )
Locale::Script::add_script ( CODE ,NAME [,CODESET] )
Locale::Script::delete_script ( CODE [,CODESET] )
Locale::Script::add_script_alias ( NAME ,NEW_NAME )
Locale::Script::delete_script_alias ( NAME )
Locale::Script::rename_script_code ( CODE ,NEW_CODE [,CODESET] )
Locale::Script::add_script_code_alias ( CODE ,NEW_CODE [,CODESET] )
Locale::Script::delete_script_code_alias ( CODE [,CODESET] )
These routines are all documented in the Locale::Codes man page.
