Top Forums Shell Programming and Scripting Help deleting leading zeros in a file Post 302856567 by rbatte1 on Tuesday 24th of September 2013 08:35:04 AM

How large is the file overall, i.e. number of records?

You could shell script it like this:-
Code:
#!/bin/ksh

typeset -i col1                     # Define as integer

while read col1 rest
do
   echo "$col1 $rest"
done < input_file  > output_file

The run time may get long if the file is large though and you will get errors if any of the values in column1 are not numeric.

Does that work as a quick hit?

Perhaps you could do something with sed or awk to strip leading zeros if the file is bigger and the alapse time of the above code is not acceptable.



I hope that this helps

NAME
DBIx::Class::Schema::Loader::RelBuilder - Builds relationships for DBIx::Class::Schema::Loader SYNOPSIS
See DBIx::Class::Schema::Loader and DBIx::Class::Schema::Loader::Base. DESCRIPTION
This class builds relationships for DBIx::Class::Schema::Loader. This is module is not (yet) for external use. METHODS
new Arguments: $loader object generate_code Arguments: [ [ local_moniker1 (scalar), fk_info1 (arrayref), uniq_info1 (arrayref) ] [ local_moniker2 (scalar), fk_info2 (arrayref), uniq_info2 (arrayref) ] ... ] This generates the code for the relationships of each table. "local_moniker" is the moniker name of the table which had the REFERENCES statements. The fk_info arrayref's contents should take the form: [ { local_table => 'some_table', local_moniker => 'SomeTable', local_columns => [ 'col2', 'col3' ], remote_table => 'another_table_moniker', remote_moniker => 'AnotherTableMoniker', remote_columns => [ 'col5', 'col7' ], }, { local_table => 'some_other_table', local_moniker => 'SomeOtherTable', local_columns => [ 'col1', 'col4' ], remote_table => 'yet_another_table_moniker', remote_moniker => 'YetAnotherTableMoniker', remote_columns => [ 'col1', 'col2' ], }, # ... ], The uniq_info arrayref's contents should take the form: [ [ uniq_constraint_name => [ 'col1', 'col2' ], ], [ another_uniq_constraint_name => [ 'col1', 'col2' ], ], ], This method will return the generated relationships as a hashref keyed on the class names. The values are arrayrefs of hashes containing method name and arguments, like so: { 'Some::Source::Class' => [ { method => 'belongs_to', arguments => [ 'col1', 'Another::Source::Class' ], { method => 'has_many', arguments => [ 'anothers', 'Yet::Another::Source::Class', 'col15' ], ], 'Another::Source::Class' => [ # ... ], # ... } AUTHOR
