Question

我想使用bash在文件中将多行合并为一行。我尝试了几乎所有提到的选项： How do I remove newlines from a text file?，但没有运气，也没有删除新行。此文件是REST API的JSON输出，并使用bash进行解析。

如何下面线合并成1行？

文件内容（实际）：

{"key":"HAM-5765","status":"Closed","components":"Web UX","affectedVersions":"ZCS 8.8.x","fixVersions":"Konrad-Zuse-8.8.10","customerFacingInfo":"[https://bug.rectify?id=35231 Bug 35231] 
* GetEffectiveRightsRequest failed when a delegated admin could not read zimbraMailHost ([https://bug.rectify?id=108536 Bug 108536])
* Had been unable to remove \"Dynamic Group\" from distribution properties page ([https://bug.rectify?id=108499 Bug 108499])
* After performing a bulk migration, the Delegated Admin user encountered an `HTTP Error 403` when attempting to download the list of provisioned accounts

文件内容（预期）：

{"key":"HAM-5765","status":"Closed","components":"Web UX","affectedVersions":"ZCS 8.8.x","fixVersions":"Konrad-Zuse-8.8.10","customerFacingInfo":"[https://bug.rectify?id=35231 Bug 35231] * GetEffectiveRightsRequest failed when a delegated admin could not read zimbraMailHost ([https://bug.rectify?id=108536 Bug 108536])* Had been unable to remove \"Dynamic Group\" from distribution properties page ([https://bug.rectify?id=108499 Bug 108499])* After performing a bulk migration, the Delegated Admin user encountered an `HTTP Error 403` when attempting to download the list of provisioned accounts

尝试了以下不同的命令：

tr -d "\n\r" < yourfile.txt
tr -d '\n' < file.txt
perl -0777 -pe 's/\n+//g' input >output
awk '/[0-9]+/ { a = a $0 ";" } END { print a }' file.txt
perl -p -i -e 's/\R//g;' filename
head -n 1 filename | od -c 
perl -pe 's/\s+//g' yourfile.txt

Answer 1

请尝试：

cat inputfile | perl -ne 'chomp;print'

长版：

$ cat inputfile

$ cat inputfile | perl -ne 'chomp;print' > outputfile
$ echo $(cat  outputfile)
