Small UNIX problem
I have a shell script that carries out an extraction process as follows:
For a given input file dummy which looks like the following:
a.txt
a 1
a 2
xnzbcnzbxcbzxncbmnzxbcmzx
546
456
45
5
6
56
a 3
b.txt
b1
b2
b3
the shell script returns two files called a.txt and b.txt followed by their corresponding content.
a.txt would contain the following content:
a 1
a 2
xnzbcnzbxcbzxncbmnzxbcmzx
546
456
45
5
6
56
and b.txt would contain the following content:
b1
b2
b3
the problem is when i run the script where the first line of dummy is not x.txt i get errors.
Example if dummy contained
asdasda
fg
grtjiogoirjtgdjkljdfslkjdf
a.txt
qwe
ert
tyu
then when i run the script i get the following ouput:
./extracter: line 8: $FILENAME: ambiguous redirect
./extracter: line 8: $FILENAME: ambiguous redirect
./extracter: line 8: $FILENAME: ambiguous redirect
but it still produces a.txt
Here is the script:
cat dummy |while read LINE
do
if [ "`echo ${LINE} |grep '.txt'$`" != "" ] ; then
FILENAME=${LINE}
continue
fi
echo $LINE >> $FILENAME
done
does anyone know how i can fix the problem.
thanks

NAME
trcs - convert text files from one codeset to other
SYNOPSIS
trcs -C | -l | -h
trcs [-s] [-f input-codeset ] [-t output-codeset ] [ file ]...
DESCRIPTION
trcs is a program for translation of text files from one codeset to other. When exact translation is impossible it tries to make approxi-
mations. For example pseudographic characters are approximated by ASCII characters in codesets that have no pseudographic characters and
characters with diacritical marks are approximated by existing characters.
If the option -s or --gen-script is given trcs will generate simple script that invokes tr(1) This is useful if you want to include this in
your script or for faster conversion of many files.
If none of -C, -s, -l, -h and their equivalents is given each file will be read assuming it is coded with codeset input-codeset On standard
output it will be recoded so to use codeset output-codeset If there is no file given trcs will act as filter. Both input-codeset and out-
put-codeset are case insensitive and default to `cp1251'.
OPTIONS
-C, --copyright
Display copying conditions and warranty information.
-s, --gen-script
Generates conversion script for given input and output encodings instead to convert text files.
-l, --list
List all known codesets with their aliases.
-h, --help
Display this help and exit.
-f input-codeset, --from[=]input-codeset
Codeset of the source.
-f output-codeset, --to[=]output-codeset
Codeset of the output.
EXAMPLES
trcs -fcyrillic -t koi8-r letter.txt
Convert letter.txt from ISO-8859-5 (cyrillic) to KOI8-R and output the result on standard output.
trcs --from cp437 --to=mik --gen-script >ibm2mik
Generates script ibm2mik for converting from CP437 to MIK.
sh ibm2mik screen.txt
Convert screen.txt from CP437 to MIK. Output the result on standard output. Without parameters ibm2mik acts as filter.
