I want to read values from a file...these are basically one word values, that is to say that the text file I want to read from contains lines of word length 1, as in:
I'm doing some bash-scripting and want to be able to print some text (just plain text) files into the new bash-scripts, created within a loop. Here's a short example of what I do:
Code: # main bash script # #!/bin/bash ##Filename variable1=10 for ((j=0;j<=40;j+=1)) do ## Create another bash-script echo "#!/bin/bash" >> bash_script_$j ... some stuff... cat file1.txt >> bash_script_$j ... some more stuff... done where the text file (file1.txt) I want to print in the the new bash script looks something like:
Code: # file1.txt # ...some stuff... logsave log some_program($variable1) mv output_$j folder_$j/ ... some more stuff...
I.e, the text file contains variables such as "$j", "$variable1" etc that are undefined. Doing the above works for creating new bash scripts (bash_script_1 - bash_script_40) but the variables are not determined. I would like, if possible, to somehow print the text in file1.txt into the new bash-scripts with the variables determined, i.e:
Code: # bash_script_1 # ...some stuff... logsave log some_program(10) mv output_1 folder_1/ ... some more stuff...
The text files I read are quite extensive so I would really prefer not having to paste them into the FOR-loop directly.
I would like to grep all values other than encrypted password from /etc/shadow fileFor example,each line consists of 8 fields separated with :/The only thing that I want not to print out is the contents between first : and second : (encrypted password)
I have to read a couple of numbers from a random.txt file. In this .txt file there are random numbers. They are separated by a space. Example if you opened test.txt:
test.txt :1 6 1 3 6 8 10 2 4
I would like to read those numbers using CAT and store them into an array:
numlen=${#num[*]} - (must be like this because it is a part of a larger program)
I trying to change a file with hundreds of entries, replacing line with "IP Address Number" for "Host Name", one for another.
this is the original: [IP Address Configuration : "172_17_27_161.SUBNET_U"] IP Address Number = 172.17.27.161Assignment Type = 8Host Name = CAST124Last Used = 1290499294000MAC Address = 1 00 16 35 74 4C 59Client Identifier = 01 00 16 35 74 4C 59and the result desired is: [IP Address Configuration : "172_17_27_161.SUBNET_U"]Host Name = CAST124Assignment Type = 8IP Address Number = 172.17.27.161Last Used = 1290499294000MAC Address = 1 00 16 35 74 4C 59Client Identifier = 01 00 16 35 74 4C 59I know how to change one character by another with sed, but not to change a line for another, because I don't know in which line number it is.
I have txt file with list of ID's and I need to insert comma in every line and then remove new line character so it'll become one long string. So to clarify, I have txt file content that looks like this.
234 5466 2356 ... and so on.
but I would like this to change to 234,5466,2356,... I looked at sed and tried to wrap my head around the commands but I guess my brain isn't smart enough. its really confusing for me. I've managed to add commas to end of line (sed "s/$/,/g" filename) but somehow I can't seem to remove new line character from each line.
I am splitting a file based on the values read from an input file. The below one is the script.
1)How do I add the header which is present in the original file to the new split files created?(For eg. pharmacyf conatins header as table column names. The new files created (ODS.POS.$pharmacyid.$tablename.$CURRENT_DATE.dat) are without the header).
2) Also the script is creating 0 byte files for the pharmacyids which are not available in the intial file? Can this be avoided?
for pharmacyf in * do tablename=`echo $pharmacyf |cut -f4 -d'.' ` while read pharmacyid do grep -w $pharmacyid $pharmacyf >> $OUT/ODS.POS.$pharmacyid.$tablename.$CURRENT_DATE.dat done< inputfile done
i got the slackware folder with my builds of my favorites packages, in /tmp i create the new versions of that packages. theres is a way in bash to replace the new ones in /tmp with the old ones in /home/user/slackware??
something like..... in /tmp: mv -i package1.tgz /home/user/slackware | and somethin to replace the old version of the app with the new one
I have a jar, and I need to replace a class in it, at this moment, I can only open it with "archive manager" and then drag and drop the new compiled class into the jar, but I think this is really boring, if I can do with with just a command ?
I am having difficulty getting sed to replace a string of text in an XML file, despite the fact that I have no trouble using grep to find that same string. Since the new string and old string to be replaced contain a lot of special characters, I thought it best to store them in variables as opposed to using a slew of backslashes:
I have a large number of log files, on a linux box, I need to cleanse sensitive data from before sending to a third party. I have used the below script on previous occasions to perform this task, and it has worked brilliantly (script was built with some help from here :-)
However, now one of our departments has sent me a CLIENT_FILE.txt with 425000+ variables! I think I may have hit some internal limit. I have tried splitting the client file into 4 with around 100000 variables in each, this still doesn't work. I'm loathe to keep splitting though as I have 20 directories with up to 190 files in each directory to run through. The more client files I make, the more passes I have to do.
I have an SQL dump, file.sql that has many references to a particular domain, d1.com. I would like to run a command that can replace every occurrence of d1.com with d2.com. I've tried looking into sed before but the man pages are quite daunting.
I am trying to find a way to replace a set of sequential numbers in a file with a different sequence using sed. This might be done easier using awk or some sort of bash script, but it seems to me there must be a way to do this easily with sed. Basically, what I am editing is a Cisco switch config. I want to change the sequence of ports to a different numbered sequence. Here is an example of what I am trying to do.I want to change for example, the file:
I have large text files with space delimited strings (2-5). The strings can contain "'" or "-". I'd like to replace say the second space with a pipe. What's the best way to go? Using sed I was thinking of this:
on creating a new perl script which replace IP address from the text file. eg. If in a file, we found any word like 11.222.333.44 then it has to be replaced to XX.XXX.333.44
I need to replace a string in a file(startup.sh) using a script(parser.sh). After running parser.sh startup.sh should be filled with nfs path like /home/vimal etc but im getting error since path contains /. how to remove this.
I am trying to write a script to access sqlplus and use the output to replace the result in another file. But I am having some issues with it (This script is just a test script and I am just trying to print the updated value.
#!/bin/bash I am not able to post the sqlplus connection, but it works. bb=$a
I can't get sed to actually change the file, clearly there's something basic not working, can anyone point me in the right direction? I know nothing about scripting. Oh yeah, all the directories have spaces which was why so elaborated.
find . -name "*epub" | while read file; do unzip -o "$file" content.opf && mv content.opf content.opf.bak && sed 's/<dc:language>UND</dc:language>/<dc:language xsi:type="dcterms:RFC4646">EN</dc:language>/' < content.opf.bak > content.opf && zip "$file" content.opf && rm -f content.* ; done

I need a shell script which gathers the data from a remote XML file and then displays it according to my needs.. I need this for my job due to the fact that I need to keep track price changes of euro, usd, gold, etc. The XML file I am talking about is located at this page: here. The reason I am posting the URL is that I need to use curl to get this file and it does NOT have newlines after each tag. I thought that that would be a problem. Here is what I need from the script: 1) curl to get the page 2) make use of sed, awk, etc. to display its contents in a more structured and readable manner as shown below:
