Using SED command in a shell script: Unterminated address regex
Hi All,

I am trying to use a sed command in a shell script in order to delete some lines in a file and I got the following error message.
I don't understand why it is not working 'cause I have tried with simple quotes, then with double-quotes, and it is not working.

sed: -e expression #1, char 4: Unterminated address regex

Here below is the code I used in my shell script:

1- First I read a Exclusion file where I retrieve in each line a Pattern
2- Then I use this pattern in sed cmd to delete the corresponding line and put the result in another file
Code:
buildGrep()
{
  nbl=`cat $exclusionFile | wc -l`
  i=1
  exclusion=`cat $exclusionFile | tail -${i} | head -1`
  exclusions="sed -e /${exclusion}/d"
  while [ $i -lt $((nbl+1)) ];
  do
         exclusions="${exclusions} -e '/${exclusion}/d'"
         i=`expr $i + 1`
         exclusion=`cat $exclusionFile | tail -${i} | head -1`
  done
  FinalExclusion=`${exclusions} <${TemporaryFile} >${aFiltered_monerrFile}`
}
aDate=`date '+%y.%m.%d_%H.%M.%S'`
aFiltered_monerrFile=Filtered_File.txt
TemporaryFile=TempFile$aDate.txt
ssh xxxx@xxxxx fgrep "2010\/03\/10" xxxxxxxxxxxxx/OriginalFile > $TemporaryFile
exclusionFile=xxxxx.dat
buildGrep

Have somebody any idea ?

Thank you in advance,
Alpha

What do you mean exactly by input and output ?

No Idea what you are doing but if you want to use shell variable in sed...
Code:
sed  '/'"${exclusion}"'/d' infile

@malcomex999:
I have tried with the simple-quote/double-quotes, but I still have the same issue:

sed: -e expression #1, char 3: Unterminated address regex

TemporaryFile=TempFile$aDate.txt
ssh xxxx@xxxxx fgrep "2010\/03\/10" xxxxxxxxxxxxx/OriginalFile > $TemporaryFile
exclusionFile=xxxxx.dat
buildGrep

But i see above, there is no filename to read from for the sed command...(in red)

Can you explain what you are trying to achieve?

Yes, because in this line, I just reteieve on Line from my exclusion file.
After that I concatene all the exclusion patterns with my sed command in green.
The real call off the sed command is in the blue line with input and output file:

Code:
buildGrep()
{
  nbl=`cat $exclusionFile | wc -l`
  i=1
  exclusion=`cat $exclusionFile | tail -${i} | head -1`
  exclusions="sed -e /${exclusion}/d"
  while [ $i -lt $((nbl+1)) ];
  do
         exclusions="${exclusions} -e '/${exclusion}/d'"
         i=`expr $i + 1`
         exclusion=`cat $exclusionFile | tail -${i} | head -1`
  done
  FinalExclusion=`${exclusions} <${TemporaryFile} >${aFiltered_monerrFile}`
}
aDate=`date '+%y.%m.%d_%H.%M.%S'`
aFiltered_monerrFile=Filtered_File.txt
TemporaryFile=TempFile$aDate.txt
ssh xxxx@xxxxx fgrep "2010\/03\/10" xxxxxxxxxxxxx/OriginalFile > $TemporaryFile
exclusionFile=xxxxx.dat
buildGrep
buildGrep()
{
  nbl=`cat $exclusionFile | wc -l`
  i=1
  exclusion=`cat $exclusionFile | tail -${i} | head -1`
  exclusions="sed -e /'"${exclusion}"'/d"
  while [ $i -lt $((nbl+1)) ];
  do
         exclusions="${exclusions} -e '/${exclusion}/d'"
         i=`expr $i + 1`
         exclusion=`cat $exclusionFile | tail -${i} | head -1`
  done
  FinalExclusion=`${exclusions} <${TemporaryFile} >${aFiltered_monerrFile}`
}
aDate=`date '+%y.%m.%d_%H.%M.%S'`
aFiltered_monerrFile=Filtered_File.txt
TemporaryFile=TempFile$aDate.txt
ssh xxxx@xxxxx fgrep "2010\/03\/10" xxxxxxxxxxxxx/OriginalFile > $TemporaryFile
exclusionFile=xxxxx.dat
buildGrep
