I'm not sure if this is more appropriate for the 'unix for dummies' or the 'unix for experts' forum because I'm new to this forum and this is the second topic I've discussed, but if you could let me know which one was more appropriate for something like this, please do!
So in tr (an ancient UNIX application), I can join all lines of a text file into one line by doing this:
Code:
tr -d '\n' <x >y
where x is the original file name with extension, and y is the new one.
This is about 10^6 times faster than the command %join! in vi, and doesn't leave a '\n' at the end.
-------------------
My question is, how to do this in a loop, say for all files beginning with a, and keep the filenames the same.
The following doesn't work:
Code:
for file in a*; do tr -d '\n' <"$file" >"$file"; done
This just turns a* into blank files.
I have a feeling that the problem is with the "$file" part, since tr might have a different format for the file name, but I'm not so familiar with tr
If anyone knows a way around this I would be very thankful
Thanks in advance!

I'm trying to create a loop that will prompt the user for 15 values, not forcing them to enter all 15. If the user enters through one or more of the prompts the null value needs to be converted to 0, otherwise set the parameter = to the value entered:
ex.

Hi,
how can I use "for" to have two loops :
this is my script :

I want to print out

But I have error message :

locale::codes::langvar
Locale::Codes::LangVar(3pm) Perl Programmers Reference Guide Locale::Codes::LangVar(3pm)NAME
Locale::Codes::LangVar - standard codes for language variation identification
SYNOPSIS
use Locale::Codes::LangVar;
$lvar = code2langvar('acm'); # $lvar gets 'Mesopotamian Arabic'
$code = langvar2code('Mesopotamian Arabic'); # $code gets 'acm'
@codes = all_langvar_codes();
@names = all_langvar_names();
DESCRIPTION
The "Locale::Codes::LangVar" module provides access to standard codes used for identifying language variations, such as those as defined in
the IANA language registry.
Most of the routines take an optional additional argument which specifies the code set to use. If not specified, the default IANA language
registry codes will be used.
SUPPORTED CODE SETS
There are several different code sets you can use for identifying language variations. 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:
$lvar = code2langvar('en','alpha-2');
$lvar = code2langvar('en',LOCALE_CODE_ALPHA_2);
The codesets currently supported are:
alpha
This is the set of alphanumeric codes from the IANA language registry, such as 'arevela' for Eastern Armenian.
This code set is identified with the symbol "LOCALE_LANGVAR_ALPHA".
This is the default code set.
ROUTINES
code2langvar ( CODE [,CODESET] )
langvar2code ( NAME [,CODESET] )
langvar_code2code ( CODE ,CODESET ,CODESET2 )
all_langvar_codes ( [CODESET] )
all_langvar_names ( [CODESET] )
Locale::Codes::LangVar::rename_langvar ( CODE ,NEW_NAME [,CODESET] )
Locale::Codes::LangVar::add_langvar ( CODE ,NAME [,CODESET] )
Locale::Codes::LangVar::delete_langvar ( CODE [,CODESET] )
Locale::Codes::LangVar::add_langvar_alias ( NAME ,NEW_NAME )
Locale::Codes::LangVar::delete_langvar_alias ( NAME )
Locale::Codes::LangVar::rename_langvar_code ( CODE ,NEW_CODE [,CODESET] )
Locale::Codes::LangVar::add_langvar_code_alias ( CODE ,NEW_CODE [,CODESET] )
Locale::Codes::LangVar::delete_langvar_code_alias ( CODE [,CODESET] )
These routines are all documented in the Locale::Codes::API man page.
