Top Forums Shell Programming and Scripting Linux Commands needed for replacing variable number of spaces with a single , in a txt file Post 303016241 by RudiC on Monday 23rd of April 2018 05:53:27 AM

Welcome to the forum.

The first place to look at is the data creator, i.e. your SQL query. Can it be modified to supply exactly what you need without correction / adaption downstream? My SQL has become a bit rusty, but there exist settings to influence the output like set colsep , or functions to remove spaces e.g. trim(). Does this help?

Re. your request: does your tr version offer the -s (squeeze) option?
Code:
tr -s ' ' ',' < file
name,age,job,

If not, we need to dive deeper and resort to a small script like for awk or similar.

SQL::Translator::Parser::DBIx::Class(3) 		User Contributed Perl Documentation		   SQL::Translator::Parser::DBIx::Class(3)

NAME
SQL::Translator::Parser::DBIx::Class - Create a SQL::Translator schema from a DBIx::Class::Schema instance SYNOPSIS
## Via DBIx::Class use MyApp::Schema; my $schema = MyApp::Schema->connect("dbi:SQLite:something.db"); $schema->create_ddl_dir(); ## or $schema->deploy(); ## Standalone use MyApp::Schema; use SQL::Translator; my $schema = MyApp::Schema->connect; my $trans = SQL::Translator->new ( parser => 'SQL::Translator::Parser::DBIx::Class', parser_args => { dbic_schema => $schema, add_fk_index => 0, sources => [qw/ Artist CD /], }, producer => 'SQLite', ) or die SQL::Translator->error; my $out = $trans->translate() or die $trans->error; DESCRIPTION
This class requires SQL::Translator installed to work. "SQL::Translator::Parser::DBIx::Class" reads a DBIx::Class schema, interrogates the columns, and stuffs it all in an $sqlt_schema object. Its primary use is in deploying database layouts described as a set of DBIx::Class classes, to a database. To do this, see "deploy" in DBIx::Class::Schema. This can also be achieved by having DBIx::Class export the schema as a set of SQL files ready for import into your database, or passed to other machines that need to have your application installed but don't have SQL::Translator installed. To do this see "create_ddl_dir" in DBIx::Class::Schema. PARSER OPTIONS
dbic_schema The DBIx::Class schema (either an instance or a class name) to be parsed. This argument is in fact optional - instead one can supply it later at translation time as an argument to "translate" in SQL::Translator. In other words both of the following invocations are valid and will produce conceptually identical output: my $yaml = SQL::Translator->new( parser => 'SQL::Translator::Parser::DBIx::Class', parser_args => { dbic_schema => $schema, }, producer => 'SQL::Translator::Producer::YAML', )->translate; my $yaml = SQL::Translator->new( parser => 'SQL::Translator::Parser::DBIx::Class', producer => 'SQL::Translator::Producer::YAML', )->translate(data => $schema); add_fk_index Create an index for each foreign key. Enabled by default, as having indexed foreign key columns is normally the sensible thing to do. sources Arguments: @class_names Limit the amount of parsed sources by supplying an explicit list of source names.
