remove lines 3

[w5000]

with slash (or multiple slashed) on the beginning of lines but also such slash(es) led and/or trailed by spaces/tabs and also lines with space in a direcotry name (usually typo)

Example of lines which should be rid off:

/
 /  dgf / dfg
   ////
///////
/sfsd/sfd /
/sfsd/sfdsfs /dfgf/df/ 
/dfgdg /gddd /

and which should NOT be removed

///sfsffs
/d/d/d/d
  /ssfsfsf

Multiple occurences of / (like in example ///sfsffs) could also be replaced by single / (/sfsffs)

I want to avoid "/" filesystem "representants" from the file.

# touch ^Uadfasd  (created using ctrl-v ctrl-u)
# ls                                                    
adfasd
# rm adfasd
rm: adfasd: A file or directory in the path name does not exist.

# set -A arr $(ls .)
# echo ${arr[*]}
adfasd
# rm ${arr[*]}
# ls

ok, I think this will do the job:

sed "s/^[[:space:]]*//;s/[[:space:]]*$//" test_file|sed s/[[:space:]]*//g|sed s,///*,/,g|grep ^\/|grep -v ^\/$

sed 's#//*#/#g' inputfile | awk '{for (i=1;i<=NF;i++) { if ($i == "/") next } ; print }'

The sed compresses multiple slashes into one. The awk part rejects lines with an isolated "/".

Note that I have allowed "/dfgf/df/" because it is perfectly acceptable to terminate a directory name with a slash; in fact in many cases preferable because it explicitly specifies a directory rather than a file.

Something like this ?

awk 'NF==1&&$1!~"^/*$"' /path/to/input

Hope This Helps, PH.

PHV, that wouldn't remove these two lines:

/sfsd/sfd /
/sfsd/sfdsfs /dfgf/df/
/dfgdg /gddd /

Really ?
awk '[!]NF==1[/!]&&$1!~"^/*$"' /path/to/input

 

[Annihilannic]

True, true... okay, but it *would* remove a line with two valid directories, e.g. "/somepath /some/other/path".

I assume that is not what the OP wanted.

Reread the 1st post ...

also lines with space in a direcotry name (usually typo)

Hmm... okay... I'll crawl back under my stone now.
