Machine Type: i686-pc-linux-gnu
Bash Version: 3.2
Patch Level: 15
Release Status: release
Description:
If a function f set a variable v to $'\001' then type f or set
add a second \001 in it's output. Hence v becomes $'\001\001'.
You'll need to use a hex viewer (in the example xxd) to see it.
Repeat-By:
f() {
v=$'\001'
}
type f | xxd

Description:
Function with a here document fails to be exported/imported
Repeat-By:
$cat bin/itk/column/itkColumnTypeGenerateCommandExampleGet.bish
itkColumnTypeGenerateCommandExampleGet()
{
cat <<-'+' | tr "\t" " " | tr -s " "
cat - | utkSort
itkSchemaToColumnType

utkSort
itkDirToColumnType \"$dirName\" | atkActiveTableLineSelect |
utkSort
+
}
$
$( . bin/itk/column/itkColumnTypeGenerateCommandExampleGet.bish ; export -f
itkColumnTypeGenerateCommandExampleGet ; echo ls | bash3 )
bash3: itkColumnTypeGenerateCommandExampleGet: line 8: syntax error near
unexpected token `|'
bash3: itkColumnTypeGenerateCommandExampleGet: line 8: ` | tr "\t" " " | tr
-s " "'
bash3: error importing function definition for
`itkColumnTypeGenerateCommandExampleGet'
aq bin columnTypes data dictionary doc _index java _remove tags
tags2 test
This is because:
$ ( . bin/itk/column/itkColumnTypeGenerateCommandExampleGet.bish ; export -f
itkColumnTypeGenerateCommandExampleGet ; set | less )
itkColumnTypeGenerateCommandExampleGet ()
{
cat <<-'+'
cat - | utkSort
itkSchemaToColumnType
atkCacheToColumnType \"$npName\" | atkActiveTableLineSelect | utkSort
atkCacheToColumnType \"$npName\" | atkTransactionTableLineSelect | utkSort
itkDirToColumnType \"$dirName\" | atkActiveTableLineSelect | utkSort
itkDirToColumnType \"$dirName\" | atkActiveTableLineSelect | utkSort
+
| tr "\t" " " | tr -s " "
}
However the shell function as defined above works fine as long as not
exported:
$ ( . bin/itk/column/itkColumnTypeGenerateCommandExampleGet.bish ; export -f
itkColumnTypeGenerateCommandExampleGet ;
itkColumnTypeGenerateCommandExampleGet )
cat - | utkSort
itkSchemaToColumnType
atkCacheToColumnType \"$npName\" | atkActiveTableLineSelect | utkSort
atkCacheToColumnType \"$npName\" | atkTransactionTableLineSelect | utkSort
itkDirToColumnType \"$dirName\" | atkActiveTableLineSelect | utkSort
itkDirToColumnType \"$dirName\" | atkActiveTableLineSelect | utkSort
$
Fix:
None that I know of.
