Full Discussion: Waiting for wildcard filename to exists in while loop

It's always dangerous to want a wildcard character as part of a filename, but you can do this:-
Code:
until [ -f Trigger\*.done ]
do
 ......

You must make sure that you escape every usage of the file name correctly, and if you are setting it as a variable, you might need to double escape it, i.e.
Code:
file="Trigger\\\*.done"
until [ -f Trigger\*.done ]
do
 ......

... so you escape the escape character too so that doesn't get interpreted on setting the variable.


I still worry that you may make a mistake with serious consequences. You might be better using a file called All_Trigger.done instead for clarity and to minimise the risks, especially of any maintenance to your code later on.

jistoeuc(1)							   User Commands						       jistoeuc(1)

NAME

       jistoeuc, jistosj, euctojis, euctosj, sjtojis, sjtoeuc - Code conversion between JIS, PC kanji, and Japanese EUC

SYNOPSIS

       jistoeuc [-8] [-U] [filename...]

       jistosj [-8] [-U] [filename...]

       euctojis [-8] [-U] [filename...]

       euctosj [-U] [filename...]

       sjtojis [-8] [-U] [filename...]

       sjtoeuc [-U] [filename...]

AVAILABILITY

       SUNWjfpu

DESCRIPTION

       For  Japanese language handling, the jistoeuc family provides conversion between different code standards. command [ filename ...] does the
       specified conversion on the contents of the input filenames and writes it to stdout.

       If filename is not given, it reads and converts characters from the standard input.

       jistoeuc        converts JIS to Japanese EUC

       jistosj	       converts JIS to PC kanji

       euctojis        converts Japanese EUC to JIS

       euctosj	       converts Japanese EUC to PC kanji

       sjtojis	       converts PC kanji to JIS

       sjtoeuc	       converts PC kanji to Japanese EUC

OPTIONS

       -8	With this option specified, the commands  jistoeuc, jistosj, sjtojis, and sjtoeuc, can support JIS X  0201  (Half-Size	Katakana).
		This 8-bit JIS code does not use ISO Shift-In and Shift-Out escape sequences.

       -U	The output is not buffered (The default is buffered output).

SEE ALSO

       iconv(1), iconv_ja(5)

NOTES

       This command can handle shift-in escape sequences for the following character sets:

		 JIS X 0208 shift-in escape - E$B, E$(B, E$@

		 JIS X 0212 shift-in escape - E$(D

		 JIS X 0201 Roman shift-in escape - E(J, E(H

		 ASCII shift-in escape - E(B

       euctojis and sjtojis can handle shift-in escape sequences for the following character sets:

		 JIS X 0208 shift-in - E$B

		 JIS X 0212 shift-in - E$(D (except when sjtojis command is specified)

		 JIS X 0201 Roman shift-in - E(J

       jistoeuc  does  not check whether or not each code in the input file is correct. Conversion with PC kanji is not based on TOG Japanese Ven-
       dors Council (TOG/JVC) Recommended Code Set Conversion Specification between Japanese EUC and  Shift-JIS.  The  iconv(1)  utility  provides
       these functions. See iconv(1) and iconv_ja(5) for more information.

BUGS

       If   JIS X  0212  character set is specified as input, jistosj and euctosj can not support the conversion correctly. euctosj, sjtoeuc, jis-
       tosj, and sjtojis can support conversion correctly only if JIS X 0208 1 ku - 84 ku is specified as input.
