-

how modified , added files revision,author , comments svn log verbose in pattern:

cat test:

r7351 | user01 | 2013-07-02 17:53:28 -0400 (tue, 02 jul 2013) | 2 lines changed paths:     d /trunk/demo/proj1/.project  jira-125723   removing unwanted files   ------------------------------------------------------------------------  ------------------------------------------------------------------------ r7352 | user02 | 2013-07-02 17:54:24 -0400 (tue, 02 jul 2013) | 2 lines changed paths:    d /trunk/demo/proj2/320-test.ert  jira-125723 removing unwanted files ------------------------------------------------------------------------ ------------------------------------------------------------------------ r7504 | user04 | 2013-07-08 14:26:36 -0400 (mon, 08 jul 2013) | 4 lines changed paths:    m /trunk/demo/maven/sum.jsp    m /trunk/demo/code/results.jsp  jira-121639  wp-iqisu- lot of changes fix issue ------------------------------------------------------------------------ ------------------------------------------------------------------------ r7523 | user08 | 2013-07-08 16:17:52 -0400 (mon, 08 jul 2013) | 1 line changed paths:    /trunk/demo/ant/properties  jira-2185[/code]

my code , output:

cat test | awk '/^r[0-9]* \|/ { revision=$1; } /  [am]/ { print revision": "$0; }' r7504:    m /trunk/demo/maven/sum.jsp r7504:    m /trunk/demo/code/results.jsp r7523:    /trunk/demo/ant/properties[/code]

but need author , comments information too. desired output:

r7504:  user04 jira-121639  modified /trunk/demo/maven/sum.jsp     wp-iqisu- lot of changes fix issue r7504:  user04 jira-121639  modified /trunk/demo/code/results.jsp  wp-iqisu- lot of changes fix issue r7523:  user08 jira-2185    added    /trunk/demo/ant/properties     

$ cat tst.awk begin{ rs="\n-+\n"; fs="\n"; ofs="\t" } /\n   [ma]/ {     sub(/^-+\n/,"")     sub(/[[:space:]]+$/,"")      split($1,hdr,/ \| /)      numfiles=0     (i=3;$i;i++) {         sub(/^ +m +/,"modified" ofs,$i)         sub(/^ +a +/,"added" ofs,$i)         file[++numfiles] = $i     }      user = $(i + 1)     sub (/\[.*/,"",user)      cmts = $(i + 3)      (filenr=1;filenr<=numfiles;filenr++) {         print hdr[1], hdr[2], user, file[filenr], cmts     } } $ $ awk -f tst.awk file r7504   user04  jira-121639     modified        /trunk/demo/maven/sum.jsp       wp-iqisu- lot of changes fix issue r7504   user04  jira-121639     modified        /trunk/demo/code/results.jsp    wp-iqisu- lot of changes fix issue r7523   user08  jira-2185       added   /trunk/demo/ant/properties

the above uses gnu awk can set rs more single character.

to understand it, add temporary intermediate "prints" variables. specific formatting of output beyond putting tab between extracted values, man awk , see printf.
