Thema: How to 'filter' on two lines, in a file ?

Hi, i'm trying to 'filter' a .po file, and make some replacements.

This is how it looks in the original test.po file:

msgid "ORIGINAL-1"
msgstr "TRANSLATION-1"


msgid "ORIGINAL-2"
msgstr "TRANSLATION-1"


msgid "ORIGINAL-3"
msgstr "TRANSLATION-1"


when i do this:



it looks like this:

msgid "ORIGINAL-1"
msgstr "TRANSLATION-2"


msgid "ORIGINAL2"
msgstr "TRANSLATION-2"


msgid "ORIGINAL3"
msgstr "TRANSLATION-2"


but this is how i want it to become:

msgid "ORIGINAL-1"
msgstr "TRANSLATION-2"


msgid "ORIGINAL2"
msgstr "TRANSLATION-3"


msgid "ORIGINAL3"
msgstr "TRANSLATION-4"


so, i tried to connect and 'filter' on two lines, like this:



but this doesn't work.

is it possible to connect and 'filter' on two lines, when the second is a new line ?
if so, how to formulate it ?

Hi Lucifer,

it looks like this:

msgid "ORIGINAL-1"
msgstr "TRANSLATION-2"


msgid "ORIGINAL2"
msgstr "TRANSLATION-2"


msgid "ORIGINAL3"
msgstr "TRANSLATION-2"

that's correct - sed replaces all hits in the file if you set the option g for global
otherwise without g it replaces one hit each line, so in your case you become the same result also without g

if you want to become that;

but this is how i want it to become:

msgid "ORIGINAL-1"
msgstr "TRANSLATION-2"


msgid "ORIGINAL2"
msgstr "TRANSLATION-3"


msgid "ORIGINAL3"
msgstr "TRANSLATION-4"

then try this;

Code:

#!/bin/bash

## Variablen ##
TMP=/tmp
TARGETFILE=$TMP/originalpo.txt
BACKUPFILE=$TMP/originalpo-backup.txt
LOGFILE=$TMP/testing.log


# Logfile loeschen (remove logfile).
rm -f $LOGFILE


# Generelles Logging (general logging).
exec 3>&1 4>&2
trap 'exec 2>&4 1>&3' 0 1 2 3
exec 1>$LOGFILE 2>&1


# Original Datei sichern (backup original file).
if [ ! -e $BACKUPFILE ] ; then
    cp $TARGETFILE $BACKUPFILE
fi

# Job beginnt (job begins).
TRANSLATION="msgstr \"TRANSLATION-"
TRANSL_COUNT=1
for line in $(grep -n "\<msgstr\>" $TARGETFILE | cut -d: -f1) ; do
    let ++TRANSL_COUNT
    echo -e "\nline to replace = line $line"
    NEW_TRANSLATION="$TRANSLATION$TRANSL_COUNT\""
    echo -e "\nNEW_TRANSLATION for line $line = $NEW_TRANSLATION"
    sed -i -e "${line}c$NEW_TRANSLATION" $TARGETFILE;
done

exit

here it works .
it works with the line numbers in a loop and i have build in first to backup the original file and also logging.
i have test it with a file with name originalpo.txt in the directory /tmp on my box, it looks as following;

Code:

sgid "ORIGINAL-1"
msgstr "TRANSLATION-1"


msgid "ORIGINAL-2"
msgstr "TRANSLATION-1"


msgid "ORIGINAL-3"
msgstr "TRANSLATION-1"


msgid "ORIGINAL-4"
msgstr "TRANSLATION-1"


msgid "ORIGINAL-5"
msgstr "TRANSLATION-1"


msgid "ORIGINAL-6"
msgstr "TRANSLATION-1"


msgid "ORIGINAL-7"
msgstr "TRANSLATION-1"


msgid "ORIGINAL-8"
msgstr "TRANSLATION-1"


msgid "ORIGINAL-9"
msgstr "TRANSLATION-1"

after use of the script it looks as following;

Code:

msgid "ORIGINAL-1"
msgstr "TRANSLATION-2"


msgid "ORIGINAL-2"
msgstr "TRANSLATION-3"


msgid "ORIGINAL-3"
msgstr "TRANSLATION-4"


msgid "ORIGINAL-4"
msgstr "TRANSLATION-5"


msgid "ORIGINAL-5"
msgstr "TRANSLATION-6"


msgid "ORIGINAL-6"
msgstr "TRANSLATION-7"


msgid "ORIGINAL-7"
msgstr "TRANSLATION-8"


msgid "ORIGINAL-8"
msgstr "TRANSLATION-9"


msgid "ORIGINAL-9"
msgstr "TRANSLATION-10"

and the logfile thereto looks as following;

Code:

line to replace = line 2

NEW_TRANSLATION for line 2 = msgstr "TRANSLATION-2"

line to replace = line 6

NEW_TRANSLATION for line 6 = msgstr "TRANSLATION-3"

line to replace = line 10

NEW_TRANSLATION for line 10 = msgstr "TRANSLATION-4"

line to replace = line 14

NEW_TRANSLATION for line 14 = msgstr "TRANSLATION-5"

line to replace = line 18

NEW_TRANSLATION for line 18 = msgstr "TRANSLATION-6"

line to replace = line 22

NEW_TRANSLATION for line 22 = msgstr "TRANSLATION-7"

line to replace = line 26

NEW_TRANSLATION for line 26 = msgstr "TRANSLATION-8"

line to replace = line 30

NEW_TRANSLATION for line 30 = msgstr "TRANSLATION-9"

line to replace = line 34

NEW_TRANSLATION for line 34 = msgstr "TRANSLATION-10"

but the strings like "ORIGINAL-1", "ORIGINAL-2", ... and "TRANSLATION-1", "TRANSLATION-2", ... are only there for example.

i know
i think you need a additional loop as example;

Code:

while read line ; do

done < /tmp/file_with_translations.txt

and in this loop you can put in the loop from post #2 this one;

Code:

TRANSLATION="msgstr \"TRANSLATION-"
TRANSL_COUNT=1
for line in $(grep -n "\<msgstr\>" $TARGETFILE | cut -d: -f1) ; do
    let ++TRANSL_COUNT
    echo -e "\nline to replace = line $line"
    NEW_TRANSLATION="$TRANSLATION$TRANSL_COUNT\""
    echo -e "\nNEW_TRANSLATION for line $line = $NEW_TRANSLATION"
    sed -i -e "${line}c$NEW_TRANSLATION" $TARGETFILE;
done

you can read line for line from a file with your new translations
this you can do with the while read loop and
after a line was read you must to allocate the line to the variable $NEW_TRANSLATION
for the second loop, but you must also change things in the second loop a little bit.

it's sure doable but it's a bit complcated.
for what is that good ?
earlier i also translated many things but i didn't need a script for that.

Thanks Pike,
i made a script to change a translation file automatically, incase of an update.
it saves a lot of time.
i can do all the changes this way, accept for the last two that are Translated with "Plugins"
and because i only know a little bit about bash commands/scripts i was wondering if it could be done (easy) with a script.

it's not a big problem, it are only two translations, and it doesn't take much time to change two translations manually.
but if it can be done, it would be nice, and i can learn someting more about the possibilities of scripts.

Hi Lucifer,

i made a solution as following;

Code:

#!/bin/bash

## Variablen ##
TMP=/tmp
TARGETFILE=$TMP/originalpo.txt
BACKUPFILE=$TMP/originalpo-backup.txt
LOGFILE=$TMP/testing.log


# Logfile loeschen (remove logfile).
rm -f $LOGFILE


# Generelles Logging (general logging).
exec 3>&1 4>&2
trap 'exec 2>&4 1>&3' 0 1 2 3
exec 1>$LOGFILE 2>&1


# Original Datei sichern (backup original file).
if [ ! -e $BACKUPFILE ] ; then
    cp $TARGETFILE $BACKUPFILE
fi


# Job beginnt (job begins).
EXTENS_1="msgid \"Extensions\""
TO_WRITE_1="msgstr \"Extensies\""
LINE_TO_REMOVE_1="$(grep -n "$EXTENS_1" "$TARGETFILE" | cut -d: -f1)"
let ++LINE_TO_REMOVE_1
echo -e "\nline (old translation) to remove = line $LINE_TO_REMOVE_1."
sed -i -e ''"$LINE_TO_REMOVE_1"'d' "$TARGETFILE"
echo -e "\nwrite new translation;\n$TO_WRITE_1\nin line $LINE_TO_REMOVE_1."
sed -i -e '/'"$EXTENS_1"'/{;a\' "$TARGETFILE" -i -e "$TO_WRITE_1" -i -e '}'

EXTENS_2="msgid \"extensions\""
TO_WRITE_2="msgstr \"extensies\""
LINE_TO_REMOVE_2="$(grep -n "$EXTENS_2" "$TARGETFILE" | cut -d: -f1)"
let ++LINE_TO_REMOVE_2
echo -e "\nline (old translation) to remove = line $LINE_TO_REMOVE_2."
sed -i -e ''"$LINE_TO_REMOVE_2"'d' "$TARGETFILE"
echo -e "\nwrite new translation;\n$TO_WRITE_2\nin line $LINE_TO_REMOVE_2."
sed -i -e '/'"$EXTENS_2"'/{;a\' "$TARGETFILE" -i -e "$TO_WRITE_2" -i -e '}'


exit

for test you can put the script on your box to the directory /tmp and name it as example test.sh and with bash /tmp/test.sh in telnet you can start it.
it's with logging and first for the following two translations only;

Code:

msgid "Extensions"
msgstr "Plugins"

msgid "extensions"
msgstr "Plugins"

if you need more translations then you can see now how it works in the script.
it works with grep which is readout the line (old translation) that must be remove with sed and parameter d
, after the line was removed sed put in a new line (new translation) after the address which sed has found - this works with parameter a
so sed search for a address as example msgid "Extensions" and put in a new line in the next line after the adress - it works good here i have test it.

here now the testfile with name originalpo.txt that i used (i put it on my e2box in the directory /tmp);

Code:

msgid "Plugins"
msgstr "Plugins"

msgid "test"
msgstr "testing"

msgid "Other Test"
msgstr "othertest"

msgid "Extensions"
msgstr "Plugins"

msgid "More Test"
msgstr "moretest"

msgid "extensions"
msgstr "Plugins"

msgid "last test"
msgstr "lasttest"

after using the script it looks as following;

Code:

msgid "Plugins"
msgstr "Plugins"

msgid "test"
msgstr "testing"

msgid "Other Test"
msgstr "othertest"

msgid "Extensions"
msgstr "Extensies"

msgid "More Test"
msgstr "moretest"

msgid "extensions"
msgstr "extensies"

msgid "last test"
msgstr "lasttest"

an at last the logfile;

Code:

line (old translation) to remove = line 11.

write new translation;
msgstr "Extensies"
in line 11.

line (old translation) to remove = line 17.

write new translation;
msgstr "extensies"
in line 17.
