[Solved] Check if file is empty with variables, bash
Hello again!
I have some trouble with scripting in bash.
In the following script I read from a folder with the files
Code:
line0_Ux.xy
line1_Ux.xy
line2_Ux.xy
.
.
.
Some of the files are empty. For those I would like to print a "0" in list.
I think the problem with the code is that bash thinks "$i_Ux" is the variable, but Im not sure..
Code:
for i in $( ls -v ); do
echo item: $i
if [ ! -s line$i_Ux.xy ]; then
echo -e "0" >> list
else
cat $i | awk '{a+=$2; n++;} END {print a/n}' >> list
done

locale::codes::langfam
Locale::Codes::LangFam(3) User Contributed Perl Documentation Locale::Codes::LangFam(3)NAME
Locale::Codes::LangFam - standard codes for language extension identification
SYNOPSIS
use Locale::Codes::LangFam;
$lext = code2langfam('apa'); # $lext gets 'Apache languages'
$code = langfam2code('Apache languages'); # $code gets 'apa'
@codes = all_langfam_codes();
@names = all_langfam_names();
DESCRIPTION
The "Locale::Codes::LangFam" module provides access to standard codes used for identifying language families, such as those as defined in
ISO 639-5.
Most of the routines take an optional additional argument which specifies the code set to use. If not specified, the default ISO 639-5
language family codes will be used.
SUPPORTED CODE SETS
There are several different code sets you can use for identifying language families. A code set may be specified using either a name, or a
constant that is automatically exported by this module.
For example, the two are equivalent:
$lext = code2langfam('apa','alpha');
$lext = code2langfam('apa',LOCALE_LANGFAM_ALPHA);
The codesets currently supported are:
alpha
This is the set of three-letter (lowercase) codes from ISO 639-5 such as 'apa' for Apache languages.
This is the default code set.
ROUTINES
code2langfam ( CODE [,CODESET] )
langfam2code ( NAME [,CODESET] )
langfam_code2code ( CODE ,CODESET ,CODESET2 )
all_langfam_codes ( [CODESET] )
all_langfam_names ( [CODESET] )
Locale::Codes::LangFam::rename_langfam ( CODE ,NEW_NAME [,CODESET] )
Locale::Codes::LangFam::add_langfam ( CODE ,NAME [,CODESET] )
Locale::Codes::LangFam::delete_langfam ( CODE [,CODESET] )
Locale::Codes::LangFam::add_langfam_alias ( NAME ,NEW_NAME )
Locale::Codes::LangFam::delete_langfam_alias ( NAME )
Locale::Codes::LangFam::rename_langfam_code ( CODE ,NEW_CODE [,CODESET] )
Locale::Codes::LangFam::add_langfam_code_alias ( CODE ,NEW_CODE [,CODESET] )
Locale::Codes::LangFam::delete_langfam_code_alias ( CODE [,CODESET] )
These routines are all documented in the Locale::Codes::API man page.
