To remove Continous blank spaces from a file in UNIX

arunkumar_mca · #1 (**permalink**) 12-08-2006

All...

I want to remove blank spaces in file . I just leraned that we can use

" cat <Input filename> | tr –s ‘ ‘ > <Target file name> "

i also know with SED we can replace a blank space by other character by

sed s/ /*/g filename.

Please let me know how can i do that by removing the space in sed

1) by modiying the new file . i mean that remove spaces in the file and store it
2) remove spaces in the file and store it in other file

Thanks in advance,
Arun.

There is no one liner as such unless you use perl. If you have the -i flag for sed, then use

Code:

sed -i -e "s/[ <tab>]*//g" in.txt
