View 4 RepliesI want to be able to check the contents of a text file for a specific string and remove it from the file from the command prompt. I would basically be searching through a number of files and if a specific string is found I would like it removed automatically. pretty much a find and replace, were the replace is nothing. any one got any ideas on how you would do this. I already have the search part sorted just need to be able to remove the string I don't want from the multiple files.

View 1 Replies View RelatedI want to delete all files within a specific folder without actually deleting the folder, what is a good bash command for this?. I found this one but encountered some errors even though I am executing it within the specific folder:
useratdebian:/home/user/folder# find . -type f -exec rm -rf {} ;
[1] 5052
useratdebian:/home/user/folder# find: missing argument to `-exec'
[1]+ Exit 1 find . -type f -exec rm -rf
The command as it appears is:
find . -type f -exec rm -rf {} ;
how to delete only the files contained within the folder called "folder" for example?
I'm trying to come up with ideas for a simple way to strip a specific "entry" from a text file.I know tools like sed and perl can remove specific lines from a file but I haven't been able to come up with an elegant way to do my group of lines.In my file, the first "Location" line and the "SVNPath" line should be unique every time... but are they enough to strip out the whole set of the group plus the trailing one line of white space separating each group? Add to this, my file will grow as new entries are added (always appended to the end) but new entries will have the same formatting.
View 9 Replies View RelatedMany folders within a subdirectory some of which have lots of data in and some of which have only one specific file called produkt.fil inside.I need a command to find and delete those folders that contain ONLY the file produkt.fil - if other files exist (doesnt matter what they are) then they should be left alone. Note: produkt.fil exists in all of the folders always.

View 4 Replies View RelatedI found such simple example of awk
Code:
awk '
BEGIN { a = "1abc 2def"
b = gensub(/(.+) (.+)/, "\2 \1", "g", a)
print b }'
However I don't understand why the regular expresion in parentheses doesn't work how I woud expect. If I delete the .+ so it does the same.
Code:
awk '
BEGIN { a = "1abc 2def"
b = gensub(/() ()/, "\2 \1", "g", a)
print b }'
I wanted to use a regular expression in parantheses like ([/+[]()]) to get the specific letters.
Code:
awk '
BEGIN { a = "1abc 2def"
b = gensub(/([/+[]()])/, "//\1", "g", a)
print b }'
But why the regexp in () isn't working

View 5 Replies View Relatedhow to remove the underlining from letters on KDE (on menus and buttons for keyboard shortcuts I think)? I am currently running Kde4.4. If this can not be done through KDE would it be possible to modify the actual font itself to remove the underlining option? I never use the keyboard to navigate and with the font I am using the underlining seems to touch the letters themselves. Also, on a side note, does anybody know what the command is to bring up the "loguout, turn off computer and restart" menu (the one that comes up when Ctrl+alt+del) are pressed?

If there is a command I can use to find specific file types? Say if I want to find all the jpg's in my home folder, but they don't have the .jpg extension in the name, how would I do it? Or can I set some kind of size parameter to find them? The ones I want are all from my digicam and roughly the same size.
