removing 2 words from file.
Hi All,

I have a text file with name of source files in that. source files ends with .mxml and .css. Now I want to remove the extensions of these source files.

Currently I can do so by writing 2 sed commands, as there are files with just 2 different extensions. But I want to do it in one sed command.

Text file contains following lines.

Code:
MS_OFFICEDEPOT_GENERIC_10.css
Video_Collatorals_Resource_Center.mxml

I want output like this one.
Code:
MS_OFFICEDEPOT_GENERIC_10
Video_Collatorals_Resource_Center

Here is my code
Code:
sed 's|.css||' file
sed 's|.mxml||' file

I want to write one line code coz there can there 3 or 4 extensions...


Thanks in advance.

Regards
-Kashif

you can try in awk
Code:
awk -F. '{print $1}' file_name

In Sed
Code:
sed 's/\..*//' file_name

Got no nice solution with sed in mind without concatenating substition cause of different patterns so maybe this is ok for you, with plain shell including a grep:

Code:
grep -E "\.css|\.mxml" infile| while read LINE; do echo ${LINE%.*}; done
MS_OFFICEDEPOT_GENERIC_10
Video_Collatorals_Resource_Center

If there is only *.css and *.mxml files, you can leave the grep out of course.

Just for completeness here an sed example in one line but not much prettier than in two lines:
Code:
sed -e 's/\.css$//g; s/\.mxml$//g' infile
MS_OFFICEDEPOT_GENERIC_10
Video_Collatorals_Resource_Center

Isn't it the while loop enough....

Code:
while read LINE; do echo ${LINE%.*}; done < infile

Hi this script can help u ...
##save the below code in a script , send filename as a parameter it will return the filename by removing the extension

Code:
#!/bin/ksh
filename=$1
pos=`expr index $filename . `
pos=`expr $pos - 1 `
rem_extn=`expr substr $filename  1  $pos `
echo "Actual Filename       : $filename"
echo "Filename without extn : $rem_extn"

I was not sure if the OP has to search explicit for *.mxml and *.css or if there are other files with different suffixes as input.
Also some of the solutions do not work properly if there is more than 1 dot in the filename.
Also if there is only those 2 suffixes, I stated in my 1st post:
