Top Forums UNIX for Beginners Questions & Answers How to change name of the file with first line of the file which has some unwanted text in it? Post 303030104 by RudiC on Wednesday 6th of February 2019 04:35:56 AM

Don Cragun's little awk script does exactly that - loop through ALL test-?????? files around, where ?????? matches the file names the sample numbers you post: 000000, 000001, 000002, etc.
If - as he explains - the echo command is removed, and the schript's output is piped through sh, all your test files should be renamed according to your spec. That is - if all files contain DIFFERENT strings as $4 in their first line. If not, files with lower numbers might be overwritten by the ones with higher number and identical $4.


EDIT: To avoid that problem, consider this small adaption of Don Cragun's script:


Code:
$ awk 'FNR == 1 {while ($4 in FNARR) $4 = $4 "_" ++CNT; FNARR[$4];  print "echo mv",  FILENAME, $4 ".log"}' test-?????? | sh
mv test-000000 SCHEDULE_REQUEST_TestCase.log
mv test-000001 SCHEDULE_REQUEST_TestCase_1.log
mv test-000002 SCHEDULE_REQUEST_TestCase_2.log
mv test-000003 SCHEDULE_REQUEST_TestCase_3.log
etc...

NAME
logcheck-test - test new logcheck rules easily SYNOPSIS
logcheck-test [-q|-i] [-a|-s|-l FILE] [-e] [-P PREFIX] [-S SUFFIX] RULE logcheck-test [-q|-i] [-a|-s|-l FILE] -r RULEFILE DESCRIPTION
logcheck-test parses a log file for matching lines specified by a single rule or a rule file. If using a single RULE you can set a PREFIX and a SUFFIX to write new rules easily. OPTIONS
-h, --help Show usage information -a, --auth.log Parse /var/log/auth.log for matching lines -s, --syslog Parse /var/log/syslog for matching lines -l, --log-file FILE Parse FILE for matching lines -i, --invert-match Show line that don't match the RULE or the RULEFILE -q, --quiet Suppress rule summary at the end of output -e, --surround-rule Surround RULE with standard prefix and suffix: ^[[:alpha:]]{3} [ :[:digit:]]{11} [._[:alnum:]-]+ RULE$ -P, --append-prefix PREFIX Append PREFIX to rule prefix. Option can be given multiple times -S, --prepend-suffix SUFFIX Prepend SUFFIX to rule suffix. Option can be given multiple times -r, --rule-file RULEFILE Use file RULEFILE for rule input EXAMPLES
With logcheck-test you can easily write and test new rules. Test a single rule against /var/log/syslog: logcheck-test -s "RULE" Test a single rule against ~/log, surround the rule with standard prefix and suffix and append "kernel " to prefix: logcheck-test -l ~/log -e -P "kernel " "RULE" Test the rules in rulefiles/linux/ignore.d.server/kernel against ~/log: logcheck-test -l ~/log -r rulefiles/linux/ignore.d.server/kernel Test which lines the rules in rulefiles/linux/ignore.d.server/kernel doesn't match: logcheck-test -l ~/log -r rulefiles/linux/ignore.d.server/kernel -i EXIT STATUS
On successful matching logcheck-test will complete with exit code 0. An exit code of 1 indicates no successful matching. An exit code greater then 1 indicates an error occurred. Textual errors are written to the standard error stream. SEE ALSO
