My question is basically the same as this previous question...
How to change all occurrences of a word in all files in a directory
...except I'm trying to change the reference to a header file.
For example,I'm trying to change [lessthan]abc/filename.h[greaterthan] to "filename.h", is this even possible using the same syntax, or should I be looking to whip myself up a quick program to do it?
Thanks
You can do it easily with sed:
sed -i -e 's,<abc/filename.h>,"filename.h",' *

My file extension is CSV file looks below format in unix server.
"Product_Package_Map_10302017.csv","451","2017-10-30 05:02:26"
"Targeting_10302017.csv","13","2017-10-30 05:02:26",
"Targeting_Options_10302017.csv","42","2017-10-30 05:02:27"
I want to delete a particular line based on filename keyword.
You can use grep -v:
grep -v '^"Product_Package_Map_10302017.csv"' file > file.filtered
'^"Product_Package_Map_10302017.csv"' matches the string "Product_Package_Map_10302017.csv" exactly at the line beginning
or sed can do it in-place:
sed -i '/^"Product_Package_Map_10302017.csv"/d' file
See this related post for other alternatives:
Delete lines in a text file that contain a specific string
See this previous question. A grep-based answer would be my first choice but, as you can see, there are many ways to address this one!
(Would have just commented, but my 'rep' is not yet high enough)
I have a file with name
ROCKET_25_08:00.csv
I want to trim the name of the file to
ROCKET_25_.csv
I tried mv but mv is not what I required because there will be cases where the files may be more than one.
I want the name till the second _.
How to get that in unix.
Please advise.
There are some utilities that provide more flexible renaming. But one solution that won't use anything other but included UNIX tools (like sed) would be:
ls -d * | sed -re 's/^([^_]*_[^_]*_)(.*)(\....)$/mv -v \1\2\3 \1\3/' | bash
This will only work in one directory, it won't process subdirectories.
It's not at all clear what you are actually trying to do, but if you just want to remove text between the last underscore and the period, you can do:
f=ROCKET_25_08:00.csv
echo ${f%_*}_.csv
I have a parameter name like
PAR="DBS_OUT"
and I have a text file(Repla.txt) with below values:
DB_TECH
DB_ADMIN
DB_TERA
DB_APS
These values in the files can defer but the parameter value will remain the same.
Now I have some Unix shell script where I need to find all such values mentioned in the file (Repla.txt)
and replace them with the parameter (PAR). Since the values in the Repla.txt is not fixed I am not able to use the sed command. for eg:
sed 's/old/new/g' input.txt > output.txt
Can anyone please help me.
Thanks
I'm not sure I completely understand what you are trying to do but if you are trying to use the values contained in Repla.txt as the strings that you want to replace in other files then the following bash line will do what you want:
PAR="DBS_OUT"; for FIND in `cat Repla.txt`; do $( find /path/to/files -name 'test?.txt' -exec sed -i "s/$FIND/$PAR/g" '{}' \;); done;
It will replace the strings contained in Repla.txt with the string DBS_OUT in all files that match test?.txt in the dir (and subdirs) /path/to/files. You will need to understand how find works.
Also note that I am not telling sed to backup, you probably want to test this out on some test files before you execute it for real. Hopefully you also have your scripts in source control so its not a big deal if you mess things up.
I hope your replacement on Capital letters only.
sed 's/DBS_[A-Z]*/DBS_OUT/g' repla.txt > destination file
or
sed 's/DBS_[A-Z]*/DBS_OUT/g' repla.txt
Im going to build a Silex/Symfony2 project and I have been looking around for a method to generate XLIFF/PO/YAML translation files based on texts-to-be-translated inside the project but not found any instruction or documentation on it.
My question is: Is there an automated way to generate translation file(s) in specific format for a Symfony2/Silex project?
If yes, please tell me how to generate the file then update the translation after that.
If no, please tell me how to create translation file(s) then adding up more text for my project? I am looking for an editor desktop based or web-based instead of using normal editor such as Transifex, GetLocalization (but they dont have option to create a new file or add more text)
After a long time searching the internet, I found a good one:
https://github.com/schmittjoh/JMSTranslationBundle
I see you've found a converter, but to answer your first question about generating your initial translation file -
If you have Gettext installed on your system you could generate a PO file from your "texts-to-be-translated inside the project". The command line program xgettext will scan the source files looking for whatever function you're using.
Example:
To scan PHP files for instances of the trans method call as shown here you could use the following command -
find . -name "*.php" | xargs xgettext --language=PHP --keyword=trans --output=messages.pot
To your question about editors:
You could use any PO editor, such as POEdit, to manage your translations, but as you say you eventually need to convert the PO file to either an XLIFF or YAML language pack for Symfony.
I see you've already found a converter tool. You may also like to try the one I wrote for Loco. It supports PO to YAML, and PO to XLIFF
Workaround for busy people (UNIX)
You can run the following command in the Terminal:
$ grep -rEo --no-filename "'.+'\|\btrans\b" templates/ > output.txt
This will output the list of messages to translate:
'Please provide your email'|trans
'Phone'|trans
'Please provide your phone number'|trans
...
I mean almost.. But you can usually do some work from here...
Obviously you must tweak the command to your liking (transchoice, double-quotes instead of single...).
Not ideal but can help!
grep options
grep -R, -r, --recursive: Read all files under each directory, recursively this is equivalent to the -d recurse option.
grep -E, --extended-regexp: Interpret PATTERN as an extended regular expression.
grep -o, --only-matching: Show only the part of a matching line that matches PATTERN.
grep -h, --no-filename: Suppress the prefixing of filenames on output when multiple files are searched.
(source)
I want to search and replace string located in a several files via bash console.
Here is the command I use to find a string in a file:
grep "string" * -r
so the above is for searching, now I need a command to replace the string.
Is that even possible?

It's cranky and difficult, but it's one way to do it.
Here's an example:
sed -i 's/ugly/beautiful/g' /home/bruno/old-friends/sue.txt
This replaces ugly with beautiful in sue.txt.
